How can we help?

On the old phone, open Settings → Your data → Export everything. Fermory saves a single .fermory file with your batches, recipes and photos; send it to yourself however you like.

On the new phone, install Fermory and choose Settings → Your data → Import. The same file works between iPhone and Android.

On iPhone, Fermory is part of your normal iCloud or computer backup. On Android, the app’s data is included in Android’s own backup where your phone supports it (large photo libraries may be left out). For a copy you control, export your journal from Settings → Your data.

Check that notifications are allowed for Fermory in your phone’s settings. Even with notifications off, due check-ins still appear on Today inside the app.

On Android, battery savers can delay reminders. For to-the-minute timing, turn on Settings → Notifications → Exact timing in Fermory.

Subscriptions are managed by the store you bought from. On iPhone: Settings → your name → Subscriptions. On Android: Google Play → Profile → Payments & subscriptions → Subscriptions.

If Plus ends, nothing is locked away: every batch keeps running with its reminders, and you can still view, edit, export or delete everything.

In Fermory, open Settings → Fermory Plus and tap Restore, signed in to the same Apple ID or Google account you bought with.

Settings → Your data → Delete all data removes everything from your phone. Deleting the app does the same. We hold no copy, so there is nothing to request from us.

No, and it never will. Fermory keeps time and keeps notes. Follow a tested recipe, and when in doubt, throw it out.

Any fermentation: kombucha, kimchi, sauerkraut, sourdough starter, water and milk kefir, yogurt, hot sauce, or a type you set up yourself.

Each batch gets its own Day count, reminders, and a timeline of what you did and saw — tastes, feeds, burps, notes, photos, and measurements like temperature, pH and salt.

Yes. Fermory is free to use with up to three batches fermenting at a time, with no ads and no account. Your history, recipes, reminders and photos are unlimited.

Yes — three at a time on the free plan, unlimited with Fermory Plus. Planned and finished batches don’t count toward the three.

Yes. A sourdough starter gets Feed and Check rise as quick actions and no end date, so it can run as long as you keep it going. Kombucha gets Taste, Bottle and Transfer, with temperature and pH readings.

Not yet. Your journal lives on your device; you can export it and import it on another phone, iPhone or Android.

No. Fermory has no accounts, no analytics and no ads. Nothing you log leaves your phone unless you export it yourself. Purchases are handled by Apple and Google.
