Terms of Service
Book of Life, operated by Sansa Technologies, Inc.
Effective September 2, 2026 · Last updated September 4, 2026
1. Who we are
Book of Life is operated by Sansa Technologies, Inc. ("Sansa," "we," "us," "our"), a Delaware corporation with a registered address at 800 North State Street, Suite 304, Dover, DE 19901, USA.
These Terms of Service ("Terms") are a binding agreement between you and Sansa covering your use of the Book of Life website at yourbookoflife.com and any related services (together, the "Service"). By signing in, you agree to these Terms. If you do not agree, do not use the Service.
Please read Section 6 carefully. It explains, in plain terms, that we are able to read what you write in Book of Life.
2. Eligibility
You must be at least 13 years old to use the Service. If you are between 13 and 18, you may use the Service only with the involvement and consent of a parent or legal guardian, who agrees to these Terms on your behalf. If you are using the Service on behalf of an organization, you represent that you are authorized to bind that organization.
3. Your account
You sign in with Google. We do not issue passwords, and we never see your Google password. You are responsible for keeping access to your Google account secure — anyone who can sign into your Google account can read your entire book.
You are responsible for all activity that occurs under your account. Tell us at team@sansatech.com if you believe your account has been accessed by someone else.
4. What Book of Life is
Book of Life is a private, once-a-year reflection tool. You write about where you are, review the commitments you made in past years, commit to what comes next, and leave notes to your past self when you re-read old entries.
The Service is provided free of charge at this time. We may introduce paid features in the future; if we do, we will tell you before charging you anything, and no existing feature that you already rely on will be taken away without notice.
Book of Life is not a medical, psychological, legal, or financial service. It is a notebook. It does not provide advice, diagnosis, or treatment, and it is not a substitute for professional help. If you are in crisis, please contact a qualified professional or an emergency service in your area.
5. Your content
Everything you write in Book of Life — your entries, commitments, reviews, events, margin notes, and anything you paste in — is "Your Content." You own Your Content. We do not claim ownership of it.
You grant us a limited, worldwide, non-exclusive, royalty-free licence to store, copy, transmit, and display Your Content solely for the purpose of operating the Service for you — storing it, showing it back to you, backing it up, exporting it when you ask, and deleting it when you ask. This licence exists only so that we can run the product. It ends when you delete Your Content or your account, except for copies remaining in routine backups, which are overwritten on the schedule described in our Privacy Policy.
We do not use Your Content to train artificial intelligence models. We do not sell it. We do not publish it. We do not show it to advertisers. We do not use it to build a profile of you for marketing.
6. We are able to see Your Content
This is the most important section of these Terms, and we would rather be blunt about it than let you assume otherwise.
Book of Life is not end-to-end encrypted. Your entries are stored in our database in a form that we can read. Encryption protects your data in transit (HTTPS) and at rest on our infrastructure providers' disks, but the keys to that encryption are held by us and our providers — not by you. There is no passphrase that only you know.
In practical terms, this means:
- A small number of Sansa personnel with database access can technically read anything you write. So can our infrastructure providers, in the same sense that any hosting company can access the data on its servers.
- We cannot promise you that no human will ever see your entries. We can only promise you how we behave, which is what the rest of this section describes.
- If we were served with a valid legal order compelling us to produce your data, we would be able to comply. A service that was end-to-end encrypted would not be able to. See the Privacy Policy for how we handle such requests.
Our commitments about access, which we consider binding:
- We access the contents of your book only when there is a specific, necessary reason: to investigate a bug or outage you or another user has reported, to respond to a support request from you, to investigate suspected abuse or a violation of these Terms, or to comply with a valid legal obligation.
- We do not read entries out of curiosity, and we do not permit staff to browse user content. Access is limited to personnel who need it to do their jobs.
- We do not use Your Content to train AI models — ours or anyone else's.
- If you want a private journal that its operator provably cannot read, Book of Life is not that product today, and you should choose a tool that offers end-to-end encryption.
We may change this in the future by adding end-to-end encryption. If we do, we will say so clearly rather than quietly.
7. The AI sorting feature
Book of Life includes one optional feature that uses artificial intelligence: you can paste a block of unstructured text, and we will suggest how to sort it into the sections of your year.
When you use this feature:
- The text you paste, along with the text of your open commitments from previous years, is sent to OpenAI, L.L.C. to produce the suggestions. It leaves our servers.
- The suggestions are only proposals. Nothing is saved to your book until you approve it. You can edit, discard, or ignore any suggestion.
- AI output can be wrong, incomplete, or nonsensical. Review it before approving it. You are responsible for what you choose to save.
- If you never use the paste feature, your text is never sent to OpenAI.
8. Acceptable use
Do not use the Service to:
- break the law, or to store content that is itself illegal to possess;
- infringe anyone's intellectual property or privacy rights;
- attempt to access another user's account or data, or to circumvent our access controls, rate limits, or security measures;
- probe, scan, or test the vulnerability of the Service without our prior written permission;
- upload malware, or otherwise interfere with or degrade the Service;
- scrape or bulk-extract data from the Service by automated means; or
- resell, sublicense, or provide the Service to third parties as your own.
We may suspend or terminate accounts that violate this section.
9. Export and deletion
You can export your entire book as a JSON file, and you can permanently delete everything, from the Settings page — at any time, without asking us and without explaining why. Deletion is a real deletion, not a hidden flag. See the Privacy Policy for what happens to backups.
10. Availability and changes to the Service
The Service is provided as-is and may change. We may add, alter, or remove features, and we may suspend the Service for maintenance. We do not guarantee uninterrupted availability, and we are not a backup service — if your book matters to you, use the export feature and keep your own copy.
We will make reasonable efforts to give notice before removing a significant feature or discontinuing the Service, and to give you an opportunity to export your data first.
11. Our intellectual property
The Service itself — the software, design, text, and branding of Book of Life and Sansa Technologies — belongs to us and our licensors. These Terms do not grant you any right to use our names, logos, or trademarks. The concept of a "book of life" as a yearly reflection practice is not ours; the implementation is.
12. Third-party services
The Service depends on third parties, including Vercel (hosting), Supabase (database and authentication), Google (sign-in), and OpenAI (the AI sorting feature). Your use of the Service is also subject to their terms where applicable. We are not responsible for the acts or omissions of third-party providers, but we do choose them, and we list them in the Privacy Policy so you know who they are.
13. Disclaimers
TO THE FULLEST EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, THAT DATA WILL NOT BE LOST, OR THAT AI-GENERATED SUGGESTIONS WILL BE ACCURATE.
Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you.
14. Limitation of liability
TO THE FULLEST EXTENT PERMITTED BY LAW, SANSA TECHNOLOGIES, INC. AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO YOUR USE OF THE SERVICE.
OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100).
These limits apply even if a remedy fails of its essential purpose. Some jurisdictions do not allow certain limitations of liability, so some of the above may not apply to you.
15. Indemnification
You agree to indemnify and hold harmless Sansa Technologies, Inc. from any claims, damages, losses, and reasonable legal fees arising out of your misuse of the Service, your violation of these Terms, or your violation of the rights of a third party.
16. Disputes, arbitration, and class action waiver
We would much rather resolve a problem directly. Before filing any formal claim, please email team@sansatech.com and give us 30 days to try to resolve it with you.
If we cannot resolve it, you and Sansa agree that any dispute arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, rather than in court. The arbitration will take place in Delaware or, at your election, remotely or in your home county. Either party may bring an individual claim in small-claims court instead.
You and Sansa each waive the right to participate in a class action or class-wide arbitration. Disputes will be resolved on an individual basis only.
You may opt out of this arbitration agreement by emailing team@sansatech.com within 30 days of first accepting these Terms, stating your name and that you are opting out of arbitration. Opting out will not affect any other part of these Terms.
17. Governing law
These Terms are governed by the laws of the State of Delaware, without regard to its conflict-of-law rules. For any dispute not subject to arbitration, you and Sansa consent to the exclusive jurisdiction of the state and federal courts located in Delaware.
Nothing in these Terms deprives you of the protection of mandatory consumer-protection laws in your country of residence.
18. Termination
You may stop using the Service and delete your account at any time from Settings.
We may suspend or terminate your access if you materially violate these Terms, if required by law, or if we discontinue the Service. Except where prohibited by law or where the violation makes it inappropriate, we will make reasonable efforts to give you notice and a chance to export your data first.
Sections 5, 6, 11, and 13 through 17 survive termination.
19. Changes to these Terms
We may update these Terms. If the change is material, we will notify you in the app or by email before it takes effect, and we will update the "Last updated" date above. Continuing to use the Service after a change takes effect means you accept the revised Terms. If you do not accept them, export your book and delete your account.
20. General
These Terms, together with the Privacy Policy, are the entire agreement between you and Sansa about the Service. If any provision is found unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver of it. You may not assign these Terms; we may assign them to an affiliate or in connection with a merger or sale of assets, subject to the Privacy Policy.
