Usme · Last updated 18 August 2026
Usme is a personal memory app. It records things you choose to give it, works out who and what is in them, and answers questions about them later. This page explains exactly what that involves, because a memory app asks for more trust than most.
Usme is made by Emrah Sayın, an independent developer.
Usme has no sign-up, no login, and no password. It does not know your name, your email address, or your phone number, and there is no server-side account holding your memories. Your memories live in a database on your device.
Two things are done by AI models that cannot run on a phone: reading a memory for the people, projects, and promises in it, and answering a question about your memories. For those, and only those, some text is sent out.
Requests go to a small proxy we operate on Cloudflare Workers, which exists so that API keys are never shipped inside the app. It forwards them to:
| Who | What they receive | Why |
|---|---|---|
| Anthropic | The text of a memory, or your question together with the handful of memories relevant to it | Extracting people and commitments; answering your questions |
| Voyage AI | The text of a memory, or of a search query | Producing the numeric representation that makes meaning-based search work |
Nothing else is transmitted. Not your audio, not your photos, not your calendar, not your contacts, and not the database as a whole.
Each installation generates a random identifier the first time it runs — a string
like 9F3C21A0-…, created on your device. It is sent with each request so
the free monthly and daily allowances can be counted.
It contains nothing about you. It is not your Apple ID, not an advertising identifier, and not linked to your name, email, or device. Deleting and reinstalling the app produces a new one, and there is no way to work backwards from it to a person.
Subscriptions are sold and processed by Apple. Usme never sees your payment details. Subscription status is managed through RevenueCat, which receives the anonymous identifier above and the fact of a purchase, so the app knows whether Pro is active. No name, email, or card information is involved.
Open Settings → Privacy and your data in the app. You can delete memories by category, or delete everything — memories, extracted people and commitments, imported files, and any pending reminders.
Because there is no account and no cloud copy, deleting in the app deletes it everywhere. Deleting the app removes everything with it.
Usme is not directed at children under 13 and does not knowingly collect anything from them.
If the data practices above change — a different model provider, or anything new leaving the device — this page and the App Store privacy label are updated together, and the date at the top changes.
