Miso

Privacy Policy

Effective November 7, 2026

Miso is a small app for couples, made by Allan Zheng, an independent developer. It's available on the App Store, and as a test version through Apple's TestFlight. This policy explains what the app keeps, where, who can see it, and how to delete it.

The short version

Your account

You sign in with Apple. Miso receives an anonymous identifier for your Apple ID and the email address Apple provides: your real email, or a private relay address if you choose Hide My Email. Miso never sees your Apple ID password. The email is only used to identify your account; Miso doesn't send you email.

What Miso stores on its server

These are kept so your partner's phone can show them.

You and your household

What you add

Health, if you connect it

Calendars, if you connect them

Money, if you connect your banks

What stays only on your phone

Who can see your information

Services Miso connects to

Only if you connect them, and always directly from your phone.

Miso doesn't send your data to these services, apart from the requests needed to read from them. You can disconnect any of them in the app's Settings, and remove Miso's access in iPhone Settings › Health › Data Access & Devices, or in your Google, Whoop, Oura or SimpleFIN account.

What Miso doesn't do

Keeping and deleting your data

Security

Everything travels to and from the server encrypted, and Supabase encrypts the database on its disks. Access is checked by the server for every request, and sign-ins are kept in the iPhone's Keychain. No system is perfectly secure, but if anything ever exposed your information, you'd be told promptly.

Children

Miso is meant for adults and isn't directed at children under 13.

Changes to this policy

If this policy changes, the date at the top will change, and the app's release notes will mention it.
