Solum
Terms of Use

The ground rules, in plain terms.

These terms govern your use of Solum. The short version: your content stays yours, use the Service lawfully, and the AIs you connect are governed by their own terms once your context reaches them. The full version follows.

Effective August 5, 2026. Last updated August 5, 2026.

PLEASE READ THIS. These Terms include an arbitration agreement and a class action waiver in Section 20. If you do not opt out within 30 days of creating your account, you and Solum agree to resolve disputes in individual arbitration rather than in court, and to give up the right to a jury trial and to participate in a class action. Section 20.7 tells you exactly how to opt out. Opting out costs nothing and does not affect your account.

Section 18 limits our liability to you.

1. Who these Terms are between

These Terms of Use ("Terms") are a binding contract between you and Nathan Ajmera, an individual doing business as Solum, located in Los Angeles, California, United States ("Solum," "we," "us," "our").

They govern your use of the Solum website at usesolum.co, the Solum web application, the Solum browser extension, the Solum desktop application, and the Solum MCP server and API (together, the "Service").

By checking the acceptance box, creating an account, or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

Our Privacy Policy is incorporated into these Terms by reference and explains how we handle your data.

2. Eligibility

You must be at least 18 years old and able to form a binding contract to use Solum. If you are using Solum on behalf of an organization, you represent that you have authority to bind that organization, and "you" means both you and that organization.

You may not use Solum if you are barred from doing so under the laws of the United States or your country of residence.

3. What Solum is

Solum is a personal context vault. You store notes, facts, preferences, saved AI conversations, and files in it. You connect AI assistants — through the Model Context Protocol or otherwise — and grant them permission to read from your vault so they arrive at a conversation already knowing what you have told Solum.

Optionally, you may connect a Google or Microsoft account so that Solum can build a searchable metadata index of your email, files, calendar, or chat.

Solum is a tool for organizing and delivering your own information. It is not a professional adviser. Nothing it or a connected assistant produces is legal, medical, financial, tax, or professional advice.

4. Your account

You are responsible for your account credentials — your password, your passkey, your recovery codes, and any device you leave signed in. Tell us promptly at solumverif@gmail.com if you believe your account has been compromised.

Recovery codes and client-encrypted content. Content you have sealed into Solum's client-encrypted tier is protected by a key derived from your passkey or passphrase that we do not hold and cannot reconstruct. If you lose your passkey, forget your passphrase, and lose your recovery codes, that content is permanently unrecoverable. We cannot reset it or recover it for you, and no legal order can compel us to. This is a deliberate property of the design, not a limitation we can waive.

Note that labelling content "high sensitivity" is not by itself what seals it. Section 5.1 of the Privacy Policy explains exactly what does, and you should read it before relying on the label.

5. Your content

5.1 You own it

You keep all ownership of everything you put into Solum — your notes, facts, conversations, files, and everything derived from them for your own account ("Your Content"). We claim no ownership.

5.2 The license you give us, and its limits

You grant us a limited, non-exclusive, worldwide, royalty-free license to host, store, encrypt, index, embed, search, transmit, display, and process Your Content solely for the purpose of operating the Service for you — including delivering it to AI assistants you have connected and to the AI providers we use to power features you invoke.

This license exists only so we can run the product. It terminates when you delete the content or your account, subject to short backup rollover periods.

We will not:

  • sell, rent, or license Your Content to anyone;
  • use Your Content to train, fine-tune, or improve any artificial intelligence or machine learning model, and we have contracted with our AI providers so they will not either;
  • use Your Content for advertising, or share it for cross-context behavioral advertising;
  • read Your Content except as described in the Privacy Policy — with your request for support, to investigate a specific security incident or abuse, or where the law requires it.

5.3 You are responsible for what you put in

You represent that you have the right to store everything you put into Solum, and that doing so does not infringe anyone's intellectual property, violate anyone's privacy, or breach any duty of confidentiality you owe.

This matters more than it usually does, because Solum is designed to ingest conversations, mailboxes, and files that contain other people's personal data. If you store personal data about other people, you are responsible for having a lawful basis to do so under any privacy law that applies to you — including obtaining consent where consent is required. If you are using Solum for work, make sure your employer permits it.

5.4 Content we generate

Solum generates summaries, titles, suggested facts, classifications, and search results from Your Content. To the extent we have any rights in that output, we assign them to you, and it is treated as Your Content. AI-generated output may not be eligible for copyright protection in some jurisdictions; that is a feature of the law, not something we control.

6. Connected AI assistants — read this before you connect one

When you connect an AI assistant and grant it access to your vault, content leaves Solum and enters that vendor's systems.

  • We cannot control what happens to it after that. The assistant vendor's own terms and privacy policy govern their retention, their use, and whether they train on it.
  • We cannot pull it back. Revoking a grant stops future deliveries. It does not undo deliveries already made.
  • You decide what each assistant can see. You control which assistants are connected and what they may read. Content held in Solum's client-encrypted tier is never delivered to any assistant, by any path — we hold only ciphertext, so there is nothing to deliver. Note that this is the encrypted tier specifically, not the "high sensitivity" label; see Privacy Policy §5.1.
  • Every delivery is logged in your audit log, which you can read and export.

Choose your connected assistants deliberately. This is the single most consequential decision you make in Solum, and it is entirely yours.

7. Connected accounts (Google, Microsoft)

If you connect a Google or Microsoft account:

  • You authorize us to access it using the read-only permissions you approve at that provider's consent screen.
  • We store a metadata index — identifiers, titles, senders, timestamps, and short snippets — and not the full bodies of your messages or files.
  • We handle Google data in accordance with the Google API Services User Data Policy, including the Limited Use requirements.
  • You can disconnect a connected account at any time from your Connections page. Disconnecting always deletes the stored tokens, revokes the grant at the provider where the provider permits it, and lets you choose whether to purge or keep the metadata index already built. You can also revoke directly at the provider — Google or Microsoft. See Privacy Policy §7.4 for exactly what each route does.
  • You must have the right to connect the account. If it is an employer-issued account, you are responsible for complying with your employer's policies.

8. Teams and organization accounts

If you use Solum through an employer or organization:

  • Your company account is separate from any personal Solum account you may have. Content does not flow between them.
  • Your organization's administrator can send company reference content to your company account. Administrators cannot read your entries — they see aggregate counts only.
  • If your seat is revoked, your company account and everything in it is permanently deleted after a 7-day grace period. Save anything you want to keep before then, and understand that content in a company account may be company property under your employment agreement — that is between you and your employer.
  • Your personal account, if you have one, is not affected.
  • The organization that pays for your seat is responsible for its administrators' conduct and for the lawfulness of what it broadcasts.

9. Acceptable use

Do not:

  • use Solum for anything illegal, or to store content that is illegal to possess;
  • store or process another person's data in violation of a privacy law, a confidentiality duty, or a contract;
  • attempt to access another user's vault, account, or data;
  • probe, scan, or test the vulnerability of the Service, or breach or circumvent any security or authentication measure, except under a written authorization from us;
  • reverse engineer, decompile, or attempt to derive the source code of the Service, except to the extent that restriction is unenforceable under applicable law;
  • use automated means to scrape the Service, or to exceed or evade rate limits;
  • resell, sublicense, or provide the Service to third parties as a service of your own, without our written agreement;
  • impersonate anyone, or misrepresent your affiliation;
  • upload malware, or use Solum to distribute it;
  • interfere with or disrupt the Service or the infrastructure behind it;
  • use Solum to develop a competing product by copying its functionality wholesale.

We may suspend or terminate an account that violates this section. Where the violation is not serious and is curable, we will try to warn you first.

10. Plans, limits, and payment

10.1 Plans and usage limits

Solum is offered in tiers for individuals and for organizations. Each tier carries usage limits on AI-powered features, including a weekly limit on Talk to Solum messages and limits on other AI-assisted operations. Current limits are shown in the app.

These limits exist because each AI-assisted operation costs us real money. We may change limits with notice. If we reduce the limits of a plan you are paying for, we will notify you at least 30 days in advance and you may cancel for a prorated refund of the unused portion.

10.2 Solum is free today

Solum is currently free. There is no paid plan, no payment processor connected to the Service, and we cannot charge you. Anything in these Terms about fees, billing, or renewal describes what will apply if we introduce paid plans — not something happening now.

10.3 If we introduce paid plans

We will not charge you for anything without first putting the price in front of you and getting your agreement to it. Specifically, before any first charge we will:

  • show you the price, the billing cycle, and what the plan includes, before you enter payment information;
  • obtain your express affirmative consent to any automatic-renewal terms, separately from your acceptance of these Terms, and send you an acknowledgment you can keep;
  • let you cancel at any time, online, from your account settings, in the same number of steps it took to subscribe, without speaking to anyone;
  • send a reminder before each renewal of an annual subscription, identifying the service, the amount, the frequency, and how to cancel;
  • give not less than 7 and not more than 30 days' clear and conspicuous notice before any price change takes effect, so you can cancel first.

If you were on a free plan when we launch pricing, we will not convert you to a paid plan automatically. You will keep a free tier or be asked to choose.

10.4 Refunds, once fees exist

Fees will be non-refundable except: where required by law; where we materially reduce a paid plan's limits under §10.1; where we terminate your account without cause under §16; or at our discretion. Cancelling stops future charges — it does not refund the current period, and your plan stays active until the period ends.

10.5 Free tiers and early access

Free and early-access tiers are provided as-is and may be changed, limited, or discontinued at any time. We will give reasonable notice before discontinuing a free tier entirely, and you will always be able to export your data first.

10.6 Taxes

Prices exclude taxes. You are responsible for any sales, use, VAT, GST, or similar taxes, other than taxes on our income.

11. Our intellectual property

The Service — the software, the interface, the design, the Solum name and logo — belongs to us and our licensors. These Terms give you a limited, revocable, non-exclusive, non-transferable license to use the Service for its intended purpose. Nothing else is granted.

You may not use our name or logo without permission, except to accurately refer to Solum.

12. Feedback

If you send us suggestions, we may use them freely, without obligation or compensation to you. You are not required to send us anything.

13. Third-party services

Solum depends on third parties — hosting, database, AI model providers, Google, Microsoft, and the AI assistants you connect. We are not responsible for third-party services, their availability, their acts or omissions, or their terms. Your use of a connected assistant or a connected account is governed by that provider's agreement with you.

If a third-party provider changes its terms, prices, or availability in a way that affects Solum, we will adapt as best we can and tell you what changed.

14. AI output — accuracy and your judgment

Solum uses AI models to summarize, extract, classify, and retrieve. AI output can be wrong. It can misremember, invent, mis-attribute, omit something important, or confidently state something false.

  • We make no representation that AI-generated output is accurate, complete, or fit for any purpose.
  • Do not rely on Solum's output for any decision that matters without verifying it yourself. That includes anything legal, medical, financial, or professional.
  • Suggested facts extracted from your conversations are suggestions. Review them. They land in your vault only after you or your settings accept them.
  • Retrieval is best-effort. Solum may fail to surface something relevant, or may surface something you would rather it had not.

You are responsible for how you use what Solum produces.

15. Availability

We aim to keep Solum available, but we do not promise uptime. The Service may be unavailable for maintenance, provider outages, or reasons outside our control. Solum is operated by one person, so support and incident response are best-effort, not around-the-clock.

Export your important data. You can export your full vault and your audit log as JSON from Settings at any time. Solum is not a backup service and should not be your only copy of anything you cannot afford to lose.

16. Suspension and termination

You may stop using Solum and delete your account at any time from your dashboard.

We may suspend or terminate your access:

  • immediately, if you materially breach these Terms — particularly §9 — or if your use creates legal risk or a security threat to us or other users;
  • on 30 days' notice, if we discontinue the Service or your plan, in which case we will refund any prepaid unused fees and give you time to export.

On termination: your license to use the Service ends. We will make your data available to you for at least 30 days — by self-service export, or on request to solumverif@gmail.com — unless we terminated you for a serious breach involving illegal content or a security threat, or unless the law requires otherwise. After that, your data is deleted as described in the Privacy Policy.

Sections 5.3, 11, 12, 17, 18, 19, 20, and 22 survive termination.

17. Disclaimer of warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED.

WE SPECIFICALLY DISCLAIM THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

We do not warrant that the Service will be uninterrupted, secure, error-free, or that AI output will be accurate.

Some jurisdictions do not allow the exclusion of implied warranties. In those jurisdictions, this section applies to the greatest extent permitted, and you may have warranty rights that these Terms do not affect. Nothing here limits the statutory rights of consumers in the EU, the UK, or any jurisdiction that grants non-waivable consumer guarantees.

18. Limitation of liability

Read this together with §18.3, which lists what is not limited.

18.1 Excluded damages

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST BUSINESS, OR LOSS OF DATA, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY.

18.2 Cap

OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED US DOLLARS ($100).

18.3 What is not limited

Nothing in §17 or §18 excludes or limits our liability for:

  • fraud or fraudulent misrepresentation;
  • willful misconduct or gross negligence;
  • death or personal injury caused by our negligence;
  • violation of law, whether willful or negligent (California Civil Code § 1668);
  • any liability that cannot lawfully be excluded or limited, including non-waivable consumer rights and statutory privacy rights under GDPR, UK GDPR, or applicable US state law.

Some jurisdictions do not allow the exclusion or limitation of certain damages. In those jurisdictions our liability is limited to the greatest extent permitted by law.

18.4 Allocation of risk

These limits reflect the allocation of risk between us and are a basis of the bargain, including in our pricing. They apply regardless of the theory of liability.

19. Indemnity

You will indemnify and hold us harmless from any third-party claim, and any resulting losses, liabilities, and reasonable legal fees, arising from:

  • your breach of these Terms, particularly §5.3 and §9;
  • content you store in Solum, including personal data about other people that you had no right to store;
  • your use of a connected AI assistant or a connected account in violation of that provider's terms;
  • your violation of any law or of anyone's rights.

We will notify you of any claim, give you control of the defense (with counsel we reasonably approve), and cooperate at your expense. You may not settle a claim in a way that imposes any obligation or admission on us without our written consent.

This section does not apply to the extent the claim arises from our own breach, negligence, or willful misconduct. If you are a consumer in a jurisdiction that restricts consumer indemnities, this section applies only to the extent permitted there.

20. Disputes — arbitration and class action waiver

This section affects your legal rights. Read it. Section 20.7 tells you how to opt out.

20.1 Talk to us first

Before starting a formal proceeding, email solumverif@gmail.com with a description of the dispute and what you want. We will do the same for you. Give it 60 days. Most things resolve here, and the limitations period is tolled while we try.

20.2 Agreement to arbitrate

If we cannot resolve it, you and Solum agree that any dispute arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration, and not in court, except as stated in §20.4 and §20.7.

Arbitration will be administered by JAMS under its Streamlined Arbitration Rules and Procedures, its Consumer Arbitration Minimum Standards, and — where applicable — its Mass Arbitration Procedures, each of which is incorporated by reference. If JAMS is unavailable or declines to administer the arbitration, the parties will agree on another established consumer-arbitration administrator, and failing agreement a court may appoint one.

The Federal Arbitration Act governs the interpretation and enforcement of this section.

20.3 How arbitration works, and who pays

  • Where: arbitration will be conducted by videoconference or on documents only, unless you request an in-person hearing, in which case it will be held in the county where you live.
  • Cost: we will pay all filing, administrative, and arbitrator fees for any claim you bring, beyond an initial consumer filing fee no greater than what it would cost to file in your local court. If the arbitrator finds your claim frivolous, fees may be reallocated under the administrator's rules.
  • Relief: the arbitrator may award any relief a court could award to you individually, including statutory damages and attorneys' fees where a statute provides for them.
  • Effect: the award is final and binding, and judgment may be entered in any court with jurisdiction.

20.4 What is carved out

Either of us may:

  • bring an individual claim in small claims court, if it qualifies;
  • seek injunctive or equitable relief in court to stop actual or threatened infringement or misappropriation of intellectual property or unauthorized access to the Service.

These carve-outs are mutual. They apply equally to you and to us.

20.5 Class action waiver

YOU AND SOLUM AGREE TO BRING CLAIMS ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate claims or preside over any class or representative proceeding.

If this waiver is found unenforceable as to a particular claim, then that claim — and only that claim — is severed from arbitration and must proceed in court. The rest of this Section 20 remains in force for all other claims. Class arbitration is not available under any circumstance.

Nothing in this section waives a right to bring a representative action that cannot lawfully be waived.

20.6 Severability within this section

If any part of §20 other than §20.5 is held unenforceable, that part is severed and the remainder of §20 continues in effect.

20.7 How to opt out of arbitration

You can opt out of §20 entirely, and it costs you nothing.

Email solumverif@gmail.com with the subject line "Arbitration Opt-Out" within 30 days of first accepting these Terms, including your name and the email address on your account. That is all. There is no form and no conditions.

If you opt out, nothing else changes — your account, your plan, and your access are unaffected. Disputes will be resolved in court under §21 instead. If you opt out, you are not bound by any future arbitration provision we add unless you agree to it separately.

21. Governing law and venue

These Terms are governed by the laws of the State of California, without regard to its conflict of laws rules.

For any dispute not subject to arbitration, the state and federal courts located in Los Angeles County, California have exclusive jurisdiction, and you and Solum each consent to that jurisdiction — except that if you are a consumer, nothing here deprives you of the protection of the mandatory consumer-protection laws of your country of residence, or of your right to bring proceedings in your local courts where the law gives you that right.

The UN Convention on Contracts for the International Sale of Goods does not apply.

22. Changes to these Terms

We will change these Terms over time. How we tell you depends on the change.

Clarifications, corrections, and changes that are neutral or better for you: we will post the updated Terms with a new version number and date. They take effect when posted.

Material changes — anything that reduces your rights, expands our rights, changes fees, or changes §18, §19, or §20:

  1. We will email you at the address on your account at least 30 days before they take effect, and show an in-app notice.
  2. We will ask you to affirmatively accept them.
  3. If you do not accept, you may terminate your account before the effective date and receive a prorated refund of any prepaid unused fees. We will not treat your silence as acceptance of a material change.

A change to §20 (arbitration) will never apply retroactively to a dispute that arose before the change, and you may opt out of any new arbitration terms under §20.7.

We keep every prior version of these Terms and will send you any of them on request.

23. General

Entire agreement. These Terms and the Privacy Policy are the whole agreement between us about the Service, and supersede any prior understanding.

Severability. If any provision is unenforceable, it is modified to the minimum extent necessary to make it enforceable, or severed if it cannot be, and the rest remains in effect. §20.5 and §20.6 govern within Section 20.

No waiver. If we do not enforce a provision, that is not a waiver of it.

Assignment. You may not assign these Terms without our consent. We may assign these Terms to a successor entity — including a corporation or limited liability company formed to operate Solum — or in connection with a merger, acquisition, or sale of assets, on notice to you.

Force majeure. Neither of us is liable for a failure to perform caused by something outside our reasonable control.

No third-party beneficiaries, except that the limitations in §17 and §18 apply for the benefit of our service providers.

Notices. We will send notices to the email address on your account; you are responsible for keeping it current. Send notices to us at solumverif@gmail.com, which is our address for notices under these Terms, including formal legal notices.

Relationship. Nothing here creates a partnership, joint venture, agency, or employment relationship.

Export and sanctions. You represent that you are not located in a country subject to a US embargo and are not on any US restricted-party list.
