In short
Zaions Engine is a backend service. You never visit it; an app of mine sends it a file you chose, it returns the result, and the file is gone. It keeps a short record that a request happened, with you and your network replaced by one-way codes.
What it receives
| Item | Why | Kept |
|---|---|---|
| The file you sent and the options you picked | To do the job you asked for | No. Deleted when the request ends; a sweeper removes any scratch file older than 2 hours |
| Your sign-in token from the app (Firebase or Supabase) | To confirm you are a signed-in user of that app, with a verified email | No. Checked and discarded |
| A Cloudflare Turnstile token | To tell a person from a script before a session starts | No. Used once |
| Your IP address | Rate limits and abuse blocking | Only as a salted one-way code of your network, never the address itself |
| In a voice room: your audio | To pass it to the other members of the room | No. Nothing is recorded |
The request history
Each request leaves one row: the app, the tool, the result, timings, byte sizes and the options from a fixed list. Your user ID and network appear only as salted one-way codes. Rows never hold a file name, file content, token or key.
Rows older than 90 days are deleted automatically.
Who else is involved
- Cloudflare runs the Turnstile check.
- Google Firebase or Supabase, whichever the calling app uses, issued your sign-in token; the engine only checks its signature against their public keys.
- The engine runs on a server I rent and manage myself. Files are not sent to any AI company or other outside service.
The apps that use it
Each calling app has its own privacy policy covering your account and what it stores. Today they are ZTools (opens in a new tab) and Rent Party.

When the engine starts receiving or keeping anything new, this page changes first and the date above moves.
