2. Scope
These terms apply to the use of the Android app "Vio Aura" (the "app"). Downloading the app and purchases via Google Play are additionally subject to the Google Play terms.
3. What the app offers
- You can log your period and get predictions for your next period, ovulation and fertile days.
- The basic features are free.
- "Vio Aura Pro" unlocks additional features (e.g. reminders, app lock, statistics and automatic backup). Pro is a one-time purchase, not a subscription. The price is shown in Google Play before you buy.
- We keep developing the app. Features may change with updates; we will not take away Pro features you have bought without an equivalent replacement.
4. Buying Pro
The purchase is made and paid for via Google Play. It is linked to your Google account and can be restored on other devices using the same account. Refunds are requested via Google Play. Your statutory consumer rights – in particular any right of withdrawal and your statutory rights for defects in digital products – remain unaffected.
5. Not a medical device
Vio Aura is not a contraceptive and not a medical device. Predictions are estimates based on your entries and may be wrong. Do not rely on the app for contraception or health decisions; talk to a doctor instead.
6. Your data and backups
All entries are stored only on your device; we have no access to them (see the privacy policy). This is why we cannot restore lost data. You are responsible for your own backups, e.g. via export or automatic backup.
7. Right of use
You receive a simple, non-transferable right to use the app for private purposes. You may not modify, decompile or resell the app unless the law expressly permits it.
8. Liability
We are liable without limitation for intent and gross negligence, for injury to life, body or health and under the German Product Liability Act. For slight negligence we are only liable for breach of an essential contractual obligation, limited to the foreseeable damage typical for this kind of contract. For the free features we are only liable for intent and gross negligence, to the extent permitted by law.
9. Dispute resolution
We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board. If you have questions or problems, please write to info@lby-it.de.
10. Final provisions
German law applies. If you use the app as a consumer, mandatory consumer protection rules of your country of residence remain unaffected. If any provision is invalid, the remaining provisions stay in effect. In case of doubt, the German version of these terms prevails.
