SlowSprout Privacy Policy

Last updated: October 27, 2026

SlowSprout (慢芽) is an offline houseplant app. We care about your privacy, and we try to know as little about you as possible.

We don't collect any data

• No sign-up or account is needed.
• We don't collect your name, email, location, contacts, photos or any other personal information.
• There are no ads, no third-party analytics or tracking SDKs, and no cross-app tracking.
• The app doesn't talk to our servers or send any data anywhere.

What stays on your device

Your plant, the days you watered it and your settings (such as sound) are stored only on your iPhone, shared between the app and its Home Screen widget, to show your plant's growth. We can't see any of it. Deleting the app deletes this data.

Things you choose to do

Tapping Feedback in the app opens your own mail app to write to us; we only receive the email you choose to send, and use it only to reply. The website and privacy links open this site in your browser. Reviews are handled by Apple's system interface.

Children's privacy

SlowSprout collects no personal information from anyone, including children.

Changes

If this policy changes, we'll update this page and the date above.
