Support

To help us solve your problem faster, please include:

• Your app version (Settings → About → Version)
• Your device and iOS version (for example, iPhone 14 · iOS 18)
• A short description of what happened and what you expected

The easiest way is to use Settings → Contact inside the app: it opens your email client with the version, language and platform already filled in.

1. What is Dendro?

Dendro is a companion app for poison dart frog (Dendrobatidae) keepers. It helps you keep track of your frogs, your live food cultures and your clutches, and reminds you when something needs attention.

2. Do I need an account? Where is my data stored?

No account and no sign-up. All your data is stored locally on your device. We do not host your collection on a server, which also means that uninstalling the app deletes your data.

Because of that, we strongly recommend exporting a backup from time to time (see below).

3. How do I back up or move my data to a new phone?

Go to Settings → Backup:

• Export data saves a single backup file that you can store in Files, iCloud Drive, or send to yourself.
• Import data restores that file on any device.

Importing replaces the data currently in the app, so export first if you are unsure. Backup and restore are PRO features.

4. What does Dendro PRO include?

• Unlimited frogs (the free plan allows 3)
• Unlimited food cultures (the free plan allows 3)
• Export and import your data
• All accent colours and themes
• Support the development of the app

PRO is available as a monthly subscription, a yearly subscription, or a one-time lifetime purchase. New users get a free trial to try everything first.

5. I already paid, but PRO is not active. What do I do?

Open Settings → PRO → Restore purchases while connected to the internet. This restores any active subscription or lifetime purchase made with your current Apple ID. If it still does not work, email us and we will help.

6. How do I cancel or change my subscription?

Subscriptions are managed by Apple, not by us. Open your App Store subscriptions, or go to iOS Settings → your name → Subscriptions, and choose Dendro.

If you buy the lifetime purchase while a subscription is still active, Apple does not cancel the subscription automatically — remember to cancel it there yourself.

7. When do notifications arrive?

Reminders are delivered at 10:00 in your local time, on the day they are due. For each food culture you get two reminders: one a few days before it expires (you choose how many days in Settings) and one on the day it expires.

They are not repeated every day during that window — the app shows the countdown on screen instead.

8. Which languages does Dendro support?

English, Spanish, German, Dutch, French, Italian and Portuguese. The app follows your device language and you can change it any time in Settings → Language.

I am not receiving notifications

Check these in order:

• In the app: Settings → Notifications must be on, plus the specific alert you expect (culture warnings, sighting alerts).
• In iOS: Settings → Notifications → Dendro must have "Allow Notifications" enabled.
• Check that a Focus mode (Do Not Disturb, Sleep) is not silencing them.
• Remember that reminders arrive at 10:00 local time on the due day — not at the moment you create the item.

The camera or photo picker does not work

Dendro needs permission to use them. Go to iOS Settings → Dendro and allow Camera and Photos.

Prices or purchases do not load

In-app purchases need an internet connection and a signed-in Apple ID. Check your connection, then reopen the app. If the problem persists, restart the device and try Restore purchases.

I lost my data after reinstalling

Data lives only on the device, so uninstalling removes it. If you have a backup file, use Settings → Backup → Import data. If you do not, unfortunately it cannot be recovered — we have no copy of it on our side.
