Terms of use
Last updated: 31 August 2026
The app
Dendra is for building mind maps. It is provided as is, with no warranty that it fits any particular purpose. Use it at your own risk and keep copies of anything that matters (Export JSON).
Free and Pro
The free version allows three maps and does not include images inside bubbles. The Dendra Pro subscription unlocks unlimited maps, images, and syncing across devices.
Subscription
- Plans: monthly or yearly, renewing automatically.
- Apple charges your App Store account when you confirm the purchase.
- It renews on its own unless you cancel at least 24 hours before the period ends.
- You can manage or cancel it in Settings › your Apple account › Subscriptions.
- Refunds are handled by Apple, under Apple's rules.
Your content
The maps are yours. We do not use them for anything. If you save them to your account or share them in a room, they are stored in our storage only to serve you and whoever you invite.
Acceptable use
Do not use the service for illegal content, or to break into, overload, or reach other people's data.
Changes and termination
These terms may change; the date above says when. We may suspend accounts that abuse the service.
