This explains what Unzen collects when you use Unzen, and what it does not.
The line we draw is specific, so it is worth stating precisely rather than broadly. We do not store what you make. We do store what you ask.
Your generated images, video and music are never written to our servers. They are delivered to your browser and kept only there. Your prompts and your chat messages are treated differently: since 3 September 2026 we keep them, so that we can investigate abuse, enforce our Terms, and answer a lawful demand. This changed a previous version of this policy, which said we kept nothing. If that distinction matters to you, read section 2 before you use the Service.
Until 4 September 2026 we kept no copy of your generated images, video or music at all. That turned out to be a promise made at your expense: if your browser's storage failed (and it does fail, for reasons neither of us controls), work you had already paid for was gone with nowhere to ask for it again.
So we now keep a recovery copy of what you generate, in storage we control, for a limited window shown in your Library. Within that window you can download it again from any device. After it, the copy is deleted automatically, and you can delete it yourself sooner from the Library. We do not use it to train anything, and only you can retrieve it.
Your uploaded reference files are not kept beyond the moment they are passed to the model.
About the provider that renders your media: we ask them to delete their copy on a schedule rather than instantly, so that a failed download can still be recovered. We cannot independently verify when they actually remove it, and we will not claim otherwise.
Your generated media and your interface settings also live in your browser's IndexedDB storage, and that copy is the one the app shows you first. We cannot read it. If you clear your browser data, switch browsers or lose the device, that copy is gone, but the recovery copy above still stands until its window ends.
Your chat history also lives in your browser, and that copy is the one the app shows you. It is not the only copy. The text of your messages is also written to our servers, as described above. Deleting a chat in your browser removes your copy, not ours. To have ours removed, see section 6.
Where the law requires a legal basis, ours is performance of our contract with you (running the account, billing), our legitimate interests (security, abuse prevention, service improvement), your consent (optional email), and legal obligation (tax and accounting records).
We do not sell your personal data, and we do not use your content to train models.
You can access, correct, export or delete your personal data, object to processing, and withdraw consent for optional email at any time. Most of it you can do yourself from your profile; for the rest, write to privacy@unzen.ai.
You can delete your account yourself from your profile. The account is locked immediately and permanently deleted after seven days; until then you can cancel from the email we send you. Deletion removes your sign-in details, your prompts and chat messages, your saved results and your support conversations, and remaining credits are forfeited. We keep payment records for as long as accounting and tax law requires, usage metering rows for billing, and any prompt that was blocked as illegal content. Deletion does not touch what is stored in your browser, which only you can clear.
You can also ask us to erase the prompts and chat messages we hold about you without closing your account. Write to the address above and we will carry it out. We may retain a narrow portion where the law obliges us to, for example material that is the subject of an active legal claim or an ongoing abuse investigation; if that applies, we will tell you.
Passwords are hashed, traffic is served over HTTPS, and access to production systems is restricted. Stored prompts and chat messages can be read only by administrators, and every read is recorded. Backups are encrypted before they leave the server.
An earlier version of this policy said that a breach of our servers could not expose a single prompt, because none were kept. Now that we keep them, that is no longer true, and we would rather say so plainly than leave the old sentence standing. It is the reason we still store no generated media at all and restrict access as tightly as we do.
Unzen is for adults only and is not directed at anyone under 18. We do not knowingly collect data from minors. If you believe a minor has created an account, write to us and we will remove it.
Our servers and our providers are located outside your country, so using the Service means your account data is transferred internationally. We use providers that offer appropriate safeguards for such transfers.
We may update this policy. Material changes are posted here with a new date. The English version is the authoritative one.
