Privacy policy

Oncepenned is a journal. This page says what is stored, where it goes, and how to get rid of it. Last updated 8 November 2026.

What we store

Where it lives

Your journal is stored on your device and synced through our database, hosted on Supabase, walled off so that only your account can reach it. Attachments are stored the same way. Our server code runs on Vercel.

On a phone, the local copy is encrypted at rest. In a browser, it is stored unencrypted on that device, so sign out on shared computers. Oncepenned is not end-to-end encrypted, because Evie could not read your journal if it were.

Who reads it

The free journal is never sent to any AI company. Writing, photos, voice notes, sync, import and export work without one.

If you add Evie (the subscription), your entries and chats are sent to Anthropic and OpenAI so she can read, search, transcribe and reply. They are processed under those companies' API terms, which do not allow training on your data. That is the only place your journal goes. Entries you mark private are kept out of everything she reads.

We do not sell your data, show ads, or share your journal with anyone else. We will hand data over only when the law requires it.

What you can do

Permissions on your phone

Camera and photos, to attach pictures. Microphone, to record voice notes. Location, only while the app is open and only if you turn it on, to remember where you wrote. Face ID, to unlock the journal on your device; your face never leaves it. Notifications, for the reminders you set.

Children

Oncepenned is for people aged 13 and over. We do not knowingly keep an account for anyone younger; if you know of one, tell us and we will delete it.

Changes and contact

If this page changes in a way that matters, the app tells you before the change applies.

Questions or requests about your data: use "Report a problem" in Settings, or email SUPPORT_EMAIL_TO_SET. Oncepenned is made by DEVELOPER_LEGAL_NAME_TO_SET.
