Legal

Terms of Service

sarn is an early-stage product run by an individual developer. These terms are written plainly and will be updated when sarn becomes a registered business or changes how it handles your data.

Effective date

Effective: 15 September 2026 · Last updated: 15 September 2026

1. Agreement

These terms are between you and sarn. sarn is operated by an individual developer and is not yet a registered business. By creating an account you accept them. If you do not, do not use sarn.

2. What sarn is

A private journal for tracking goals. You write entries; if you have connected your own AI provider key, sarn sends those entries to that provider to produce a polished version, per-goal progress notes, and a running summary of themes.

sarn is a personal productivity tool. It is not a medical device, not therapy, and not a source of medical, psychological, legal or financial advice. If you are struggling, please talk to a person — the app shows crisis resources when entries appear to touch on self-harm, and those resources are the right thing to use, not the app.

3. Your account

  • You must be at least 16 years old.
  • One account per person. Keep your password to yourself; you are responsible for what happens under your account.
  • Give us a real email address — it is the only way we can reach you about your account or reset your password.
  • You may delete your account at any time from Settings → Your data. It is immediate and permanent.

4. Your content stays yours

You own everything you write in sarn. We claim no ownership of it.

You grant us only the narrow licence needed to run the service for you: to store your content, to display it back to you, and — when you have configured an AI key and saved an entry — to transmit it to the AI provider you chose. Nothing else. Specifically, we do not use your content to train AI models, and we do not sell it, publish it, or share it for advertising.

5. The AI part, and its limits

You bring your own API key from a third-party provider. Three consequences you should be clear about:

  1. You are their customer, not just ours. Their terms and privacy policy govern what happens to text sent to them, and their bill is yours. We are not responsible for their availability, output, pricing, or data practices.
  2. AI output can be wrong. Polished entries can misstate what you wrote; progress notes and themes are inferences, not facts. Read them as a draft, never as a record. Your raw text is never overwritten — the original is always kept exactly as you typed it, and you can always see it.
  3. You are responsible for your key. We encrypt it at rest and only ever send it to the base URL you saved it against, but if you paste a key with more permissions than it needs, that is a choice with consequences.

6. Acceptable use

Do not:

  • break the law with it, or use it to harm someone;
  • upload other people’s personal information without a right to;
  • attempt to access another user’s data, probe or disrupt the service, or work around rate limits and quotas;
  • resell, sublicense, or automate sarn as a backend for another product;
  • scrape it, or run automated clients against it beyond ordinary personal use.

We apply rate limits to the operations that trigger AI calls. Circumventing them is a breach of these terms.

7. Availability

sarn is provided as is and as available. It is run by one person on modest infrastructure. There is no uptime guarantee, no support SLA, and maintenance may occasionally interrupt it.

We take nightly backups and keep them for 14 days, but backups are our operational safety net, not a service we provide to you. We will not restore an individual account, and we may lose data. If your writing matters to you — and it should — export it periodically from Settings → Your data.

8. Changes to the service

We may add, change or remove features. If we discontinue sarn entirely, we will give you at least 30 days’ notice by email and time to export your data.

9. Suspension and termination

We may suspend or close an account that breaches these terms, or where required by law. Where it is reasonable and lawful to do so, we will tell you why and give you a chance to export first.

You may leave at any time, for any reason, without telling us why.

10. Warranties

To the fullest extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that sarn will be uninterrupted, error-free, or that AI output will be accurate or useful.

11. Liability

To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, nor for lost profits, lost data, or the cost of substitute services.

Our total liability for any claim is limited to the fullest extent permitted by law. sarn takes no payments today, so for virtually every user that liability is nominal in practice.

12. Indemnity

You agree to indemnify us against claims arising from your content, your use of sarn, or your breach of these terms.

13. Governing law

sarn is not yet a registered business, so these terms do not name a governing jurisdiction. Disputes will be handled in good faith, and formal governing-law terms will follow once sarn becomes a registered business.

14. Changes to these terms

We may update these terms. Material changes will be notified by email or in the app before they take effect; continuing to use sarn afterwards means you accept them.
