Field Notes is a private Android app for a small group of family users. This page explains what the app keeps on the phone, what leaves the phone, and how to remove it.
Recordings, transcripts, summaries, details you type and reminders are stored on your phone. The app does not have user accounts of its own, and its screens do not show ads.
If you connect cloud transcription and ask the app to transcribe a recording, the audio is sent to a private service run by the app owner on Cloudflare. The service passes it to speech and text models hosted on Cloudflare Workers AI: a Deepgram speech model (with an OpenAI Whisper model as fallback) for the transcript, and a Meta Llama model for the short summary. Cloudflare's model pages describe all three models as Cloudflare-hosted with "zero data retention", and Cloudflare states that it does not train models on Workers AI customer content. This page makes no further promise about what the model makers themselves receive. Cloudflare's own Workers AI data usage page and privacy policy apply to anything beyond that.
The service does not save the audio. It keeps the finished transcript and summary in a per-user store so a retry of the same request returns the same result. That copy is meant to expire after 24 hours. The service deletes expired copies on the user's next request to it and through a scheduled cleanup, so a copy can stay longer than 24 hours if the cleanup has not yet run. Copies created before this cleanup was added stay until that user's phone next contacts the service. Your phone keeps its own copy of the note.
The service also keeps what it needs to control access and cost: a hash of your phone's access token, the device name the app supplied when it asked for access, the request date and approval status, hashed one-time enrolment codes, and daily usage counters. These access records do not hold recordings, your name, phone number or location; the transcript and summary are kept separately, as described above. If a request fails, an error message may be written to Cloudflare's service logs; it does not contain the audio.
Connecting only requests access; no audio is sent to the transcription service until you transcribe a recording. If you do not use cloud transcription, the app sends no audio to that service. (Audio can still leave the phone if you choose to share or export it; see below.)
If you tap "Connect Google Calendar", the app asks Google for one permission: to create and manage a calendar that the app itself created (the scope calendar.app.created). It cannot see your other calendars. When you choose to log a visit, the app sends that event's title, the details you typed, a line saying it was recorded with Field Notes and how long it was, and its start and end times to the Field Notes calendar in your Google account. It does not send the recording or the transcript. Your Google email is shown in Settings so you can see which account is connected. Sign-in uses Google's sign-in library on the phone.
The app also offers "Log this visit in Calendar", which opens your phone's calendar app with a prefilled event. Field Notes hands that app the same event details listed above (title, typed details, a recorded-with line and times) but not the recording or transcript. You review and save it there. Whatever calendar app you use then handles it under its own privacy policy, and it does not go through Field Notes' Google connection.
The app's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Apart from the optional features described above, notes, audio and exports leave the phone only when you choose to share or save them, for example to WhatsApp or a file. What the receiving app or person does with them is up to them.
The app shows notifications for recording status and for reminders you set. These are created on the phone.
Field Notes is not intended for children.
