Privacy Policy
SipFern is a water reminder app where a garden of plant friends grows as you log water. We built it to collect as little as possible. This page explains exactly what the app and our server keep.
Using SipFern without an account
You can use every feature without signing in. Then everything stays on your device only: your water log, daily goal, reminder times, language and unit, and your garden. We do not receive any of it.
During setup you may enter an age group, activity level and, optionally, your weight. These are used only on your device to suggest a daily goal and are not saved.
Reminders are scheduled on your device. We do not run a push notification service.
Signing in (optional)
Signing in with Google or Apple backs up your data and syncs it between your devices. When you sign in we store:
- An account identifier from Google or Apple (a random ID, the “subject”). We do not store your email address, name or photo.
- Your synced data: the actions you take in the app (water logged, goal changes, plants sown, moved or named, and similar game actions), so another device can rebuild the same garden.
- Sign-in sessions: a random ID for each device you sign in on, and when it was last used, so we can keep you signed in and let you sign out.
- Your Premium status: whether your SipFern Premium subscription or lifetime purchase is active.
Purchases
Purchases are handled by the App Store or Google Play. We use RevenueCat to check them. RevenueCat receives your purchase records from the store and your SipFern account ID; it does not receive your water log or garden. We never see your payment details.
What we do not do
- No advertising and no ad tracking.
- No analytics or crash-reporting services.
- We do not sell or share your data. SipFern is not a medical app and gives no medical advice.
Service providers
- Cloudflare carries traffic to our website and server and protects it from abuse. It processes your IP address for that purpose.
- Our server runs on a virtual private server. Your IP address is used briefly in memory to limit repeated sign-in attempts and is not stored.
- Backblaze B2 stores encrypted database backups, which are deleted automatically after about 31 days.
- Google Sign-In and Sign in with Apple confirm who you are when you sign in.
Deleting your data
- Without an account: delete the app; its data is removed from your device.
- With an account: in the app, open Settings → Account → Delete account. This deletes your account and all synced data from our server immediately and signs out every device. Encrypted backups that still contain it expire within about 31 days. Deleting your account does not cancel a subscription; manage that in your App Store or Google Play settings.
You can also email privacy@sipfern.com to ask what we hold about you or to have it deleted.
Children
SipFern does not ask for a name or contact details. Younger users are not asked about weight or activity.
Changes
If this policy changes, we will update this page and the date above.
