Postcard privacy

Last updated 26 September 2026. Covers Postcard Video, the Postcard iPhone app, including the TestFlight beta, and this website.

Postcard is made by one person, Adam Raabe. If anything here is unclear, email hi@postcardvideo.app and ask.

The chat

The chat is Claude, an AI made by Anthropic. When you send a message (or finish a take, if you turn on Comment after each take in Settings), the app sends text to a server I run so Claude can answer. It sends your message, your bullet points, the recent conversation, what you wrote under About you in Settings, the words in any files or photos you add, and what the phone heard you say in your takes (the words, never the audio). That is the whole list.

The app asks before the chat sends anything. On the first screen you can choose to use it without the chat, and you can turn the chat off or on any time in Settings, under Chat with Claude. With it off, nothing is sent.

The server passes that text to Anthropic's Claude API for the answer and sends the answer back. Anthropic's commercial API terms say they do not train their models on API traffic; their policy is at anthropic.com/legal/privacy. My server keeps no copy of your messages. It does keep, for each phone, a count of chat messages and roughly what they cost me, so the free part can be counted. That is stored against the ID Apple gives the app on your phone, which is not tied to you, your Apple account or your phone's hardware.

The server runs on Cloudflare, so Cloudflare sees what any web server sees: an IP address and a time. Those logs are not used to build a profile of anyone.

Your videos

Every take is recorded on your phone and saved to your Photos library (you can turn that off in Settings). The app never uploads a video, audio or picture on its own; the only way one leaves is if you attach it to a bug report yourself. The transcription of what you said runs on the phone with Apple's on-device speech recognition; the audio does not leave the phone for that either.

Share makes a folder on your phone with the takes, their transcripts, the chat and your bullet points. It goes only where you send it, with AirDrop or the share sheet.

Bug reports

Settings has Report a bug, and this website has a feedback form. If you send one, it goes to a server I run and I read it. It carries your words, anything you attach (a screenshot, a screen recording, or a take), your name and email if you give them, and from the app also the app version, the phone model and the chat ID above, so I can lift the chat limit for you if you ask. Reports are kept in a private GitHub repository and attachments in private Cloudflare storage, behind links only I can open. Nobody else reads them.

Permissions

The app asks for the camera and the microphone to record, and for Photos to save your takes there and to pick a photo to add to the chat. It reads nothing else from your library.

The beta

While the app is in beta it is installed through Apple's TestFlight. TestFlight collects crash logs from beta builds and lets you send me feedback and screenshots if you choose to. If you do, I see what you wrote, the screenshot, and the device and iOS version it came from. Apple's own privacy policy covers TestFlight itself.

This website

postcardvideo.app counts visits with PostHog, so I can see how many people come by and which pages they read. It records pages viewed, the site that sent you, your browser and a rough location from your IP address. It is not used for advertising and is not linked to the app. The site is hosted on Vercel, which keeps ordinary server logs.

What is not here

No accounts. No analytics inside the app. No advertising. Nothing sold or shared with anyone, ever.

Changes
