Terms of Use
Effective 30 October 2026, for NoteHero on Android
1. Trial
- You get a 14-day full-featured trial from the first time you open the app. No card is needed.
- When the trial ends without a purchase, every notebook still opens, edits and exports, but pages and exports carry a watermark, you can only create a notebook while you have fewer than 3, and you cannot make notebooks from PDFs or add pages.
2. Plans
- Yearly: a subscription that renews every year at the same price until you cancel. Payment is charged to your Google Play account when you confirm the purchase and at each renewal.
- Lifetime: pay once and keep it, including later versions.
- Prices are shown in the app and on Google Play. Google Play handles payment.
- A purchase belongs to your Google account and works on Android devices with that account. It is not shared with the iPad and iPhone version.
3. Cancelling and refunds
- Cancel in the Google Play app → your profile picture → Payments & subscriptions → Subscriptions. After cancelling, the plan works until the end of the paid period.
- Refunds follow Google Play's policy.
4. Your content
- Your notebooks and what you create are yours and stay on your device. See the Privacy Policy.
- Keeping backups is up to you. Deleting the app deletes the notebooks inside it; the
.noteherocopies in Documents/NoteHero remain.
5. Limitation of liability
The app is provided as is. To the extent the law allows, we are not liable for indirect damage from using it, including loss of data.
6. Changes to these terms
When these terms change, the date at the top of this page is updated.
