Privacy Policy

One Lamp · last updated 6 November 2026

This page says, as plainly as possible, what we keep and why. If something here is unclear, write to us and we will explain it.

1. What we collect

What	Why	How long
A random identifier stored in your browser	So the app knows it is you coming back; it is not your name or email	Until you clear your browser or ask us to delete it
What you write (a wish, a message)	To answer you and to show it back to you	Until you ask us to delete it
The questions you ask the Tiger	To keep the conversation coherent	Until you ask us to delete it
Payment status (paid / not paid, plan, period)	To unlock what you paid for	As long as records are needed for tax

We do not ask for your name, phone number, address or date of birth, and we do not buy data about you from anyone.

2. What we never do

We do not sell your data.
We do not publish what you write.
We do not show ads or use advertising trackers.
We do not use your entries to train our own models.

3. The AI part — please read this one

Replies are generated by large language models run by third-party providers. To produce an answer, the text you type is sent to one of those providers and processed there. We do not send them your payment details or your identifier. Their handling of that text is governed by their own terms and privacy policies. We keep provider agreements that prohibit using submitted content to train their public models, but we cannot technically guarantee a provider's internal behaviour — so please do not type anything you would not put in an ordinary email.

4. Payments

Card details are entered on our payment provider's checkout and never reach our servers. We only receive a confirmation that a payment succeeded, the plan, and the period it covers.

5. Who else sees your data

Our hosting provider, which stores the database.
The language-model providers described above, for the length of a request.
Our payment provider, for the transaction only.

That is the whole list. We do not share data with anyone else unless the law compels us.

6. Your rights

Wherever you live, we will honour these on request:

See what we hold about you.
Delete it. Deleting removes your entries, your subscription record and your identifier.
Export it in a readable file.
Object to a particular use.

Write to privacy@onelamp.app and we will answer within 30 days.

7. Cookies and local storage

We use no advertising cookies and no third-party analytics. The app stores a small amount of data in your browser (your identifier, and the state of today's lamp) so it works without an account.

8. Children

One Lamp is not intended for anyone under 16. If you believe a child has used it, write to us and we will delete the data.

9. Changes

If this policy changes in a way that matters, the date at the top changes and, where we can, we will tell you in the app.
