Enterdeck privacy policy
Effective 7 November 2026.
Enterdeck is a calculator. It has no account, no advertising, no analytics and no tracking, and we, its makers, receive nothing from it.
What stays on your device
Your calculator's state, its stack, variables, programs and settings, is saved on your device. Like any app's data, it is included in your device's backups if you back up your device. The keys you enter for the cloud model and Wolfram|Alpha are kept in your device's Keychain and are never sent anywhere except to the service they belong to.
What leaves your device, and only when you ask
Nothing is sent over the network unless you do one of the following.
| When you | Sent to | What is sent |
|---|---|---|
| Ask the cloud model in the Ask sheet | Anthropic, with your own API key | the words you typed; the kinds of values on the stack (for example "real number", "list of 3"); the values themselves only if you switch on "Send the values on the stack" for that ask; and results the model computes on a scratch copy of the calculator that holds none of your variables |
| Look something up, run a program that uses WA, or ask the cloud model, which may try a query while it writes a program | Wolfram|Alpha, with your own AppID | the query |
| Ask the on-device model | nowhere: it runs on your device |
Your use of Anthropic and Wolfram|Alpha is under your own agreement with each, and their terms govern what they do with what they receive:
- Anthropic: its Commercial Terms, which cover API keys (https://www.anthropic.com/legal/commercial-terms), and its privacy policy (https://www.anthropic.com/legal/privacy)
- Wolfram|Alpha: its privacy policy (https://www.wolfram.com/legal/privacy/wolfram/)
We do not operate servers for Enterdeck, and nothing passes through us.
Files you share
When you export your programs, the app writes a text file and hands it to the system's share sheet; where it goes is your choice. When you import a file, it is read on your device.
Children
Enterdeck collects nothing from anyone, children included.
Changes
If what the app sends ever changes, this policy will change first, with the date above.
