Deleting your data

Last updated: 31 August 2026

Short version

OneFill stores your information on your own phone, not on our servers. Deleting it is immediate and entirely under your control — there is no account to close and no request to submit. Uninstalling the app removes everything.

What OneFill holds, and where

Data	Where it lives	How to delete it
People you save — names, dates of birth, contact details, ID numbers, medical details, custom notes, signatures	On your device only. Never sent to us.	In the app: press and hold the person on the home screen, then confirm. Or uninstall.
Saved forms and their page images	On your device only.	In the app: Past forms → open the form → Delete. Or uninstall.
Photographs of forms you scan	Sent to our server and to OpenAI to read the page. Never stored — held in memory for one request, written to no disk and no database.	Nothing to delete: no copy is kept.
Subscription and purchase records	Held by Google Play and RevenueCat, tied to a random anonymous identifier — not to your name or email.	Retained by Google as a billing record. See below.

How to delete your data

Delete one person

Open OneFill, then press and hold the person on the home screen. A confirmation appears; confirm it. That person and everything saved about them is removed from the device permanently.

Delete one saved form

Open OneFill → Past forms → open the saved form, then choose Delete. The form and its page images are removed permanently.

Delete everything

Uninstall OneFill. On most Android phones: press and hold the OneFill icon → Uninstall; or Settings → Apps → OneFill → Uninstall. Every profile, saved form and page image is deleted with the app. Nothing is retained by us, because none of it was ever sent to us.

What is kept, and for how long

• Nothing on our servers. OneFill's service has no database. Form images exist only for the moment they are being read, and are never written to disk.
• OpenAI receives the page image in order to read it, and may hold API data briefly for abuse monitoring under their own terms. We do not permit it to be used to train models.
• Purchase records are kept by Google Play and RevenueCat as required for billing, tax and refund purposes, and are tied to a random anonymous identifier rather than to you. To cancel a subscription, use Google Play → Subscriptions. Refunds are handled by Google under Play's refund policy.
• Brief technical records. Our server keeps IP addresses in memory only, for rate limiting. They are never written to disk and disappear when the service restarts.
