2. The essentials

3. The app

Storage on your device

Your children's first names and the chosen form of address (girl, boy or neutral, for the opening of the letters), tooth diary entries (for example dates, notes, what the tooth fairy brought), dentist appointments and recorded visits, settings (including the parent question you set), photos and the PDF files you create are kept in the app's storage on your device. They are not transferred to us. If you delete the app, this data is deleted from the device.

Camera and photos

The app only accesses the camera when you take a photo, and only the photos you select yourself. When saving, the app reduces the photo's size on your device; additional information such as the location is removed. The fairy-dust photo is edited on your device. The app saves to your photo library only if you explicitly choose to. Photos are not transferred to us.

Backup file

“Create backup file” creates a file with your entries and photos on your device. You decide where to keep it (for example in your files app or a cloud service of your choice); that service's terms then apply. We do not receive the file.

You can protect the backup with a password. It is then encrypted on your device, and without the password nobody can open it, including us. Keep the password safe: if it is lost, the backup cannot be restored. Without a password the file is not encrypted; keep it especially carefully, as it contains photos and first names.

Device backups

Depending on your device settings, iCloud (Apple) or Google backup may save the app's data in your Apple or Google account. You control this in your device settings. We have no access to it; Apple's or Google's terms apply. Google backups are limited in size, so photos may not be fully backed up there. To move everything to a new device, use the backup file.

Reminders

If you turn on reminders (for example for the tooth fairy's visit in the evening or for a dentist appointment), the app schedules local notifications on your device. Your device asks for permission. No data is sent to us or to a notification service.

In-app purchase

You buy the complete pack through Apple's App Store or Google Play. Apple or Google is your contractual partner for payment; their privacy policies apply. Codes for the complete pack (for example from a promotion) are also redeemed with Apple or Google.

To check whether a purchase exists and to restore purchases, we use the service of RevenueCat, Inc., 1032 E Brandon Blvd #3003, Brandon, FL 33511, USA. The following is processed:

RevenueCat does not receive names, photos, diary entries, email addresses or payment data. The legal basis is the performance of the contract (Art. 6 (1) (b) GDPR). We have a data processing agreement with RevenueCat; transfers to the USA are based on the EU Standard Contractual Clauses.

Ratings and recommending

The app may show Apple's or Google's rating dialog at most twice. You rate directly with Apple or Google; we receive no data about you. If you tap “Recommend Perlina”, your device's share menu opens with a link to perlina.app. We do not learn whom you send it to.

Links from the app

Help, privacy, legal notice and the link to our app Wichtelmorgen open in your device's browser or app store, after the parent question. Section 4 applies to the website.

No medical advice

Perlina is not intended to detect, monitor, treat or prevent any disease and does not replace a visit to the dentist.

4. The website

The website is delivered via Cloudflare by Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA. When you visit, Cloudflare processes technically necessary data such as IP address, date and time, the page requested and browser type, in order to deliver the site and protect it from attacks (Art. 6 (1) (f) GDPR).

We have a data processing agreement with Cloudflare (part of Cloudflare's terms). Cloudflare is certified under the EU-US Data Privacy Framework; transfers to the USA rely on it (Art. 45 GDPR).

The website uses no visitor statistics, no advertising or analytics services and sets no cookies. Fonts are loaded from our own server.

5. Contact by email

If you write to us, we process your email address and your message in order to reply (Art. 6 (1) (b) or (f) GDPR). We delete them once the request has been dealt with and no retention obligations apply.

6. Your rights

You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object to processing based on legitimate interests (Art. 21). Write to us at hallo@perlina.app.

You can also lodge a complaint with a data protection supervisory authority, for example the Brandenburg data protection commissioner (Landesbeauftragte für den Datenschutz und für das Recht auf Akteneinsicht Brandenburg), Stahnsdorfer Damm 77, 14532 Kleinmachnow, Germany, or the authority in your country.

7. Having your data deleted

Perlina does not need an account. This is how your data is deleted:

  1. Data on your device (first names, form of address, diary, photos, appointments, settings, PDFs): delete the app. This removes the data from the device. We never received it.
  2. Backup files and device backups: delete backup files wherever you saved them. You manage device backups in your Apple or Google account.
  3. Purchase data at RevenueCat (anonymous app identifier and receipt): email hallo@perlina.app with the subject “Deletion Perlina” and include the order number from Google's purchase confirmation (starts with “GPA.”) or from Apple. We delete the entry within 30 days and confirm the deletion.

Afterwards a purchase can only be linked again via “Restore purchases”. Apple or Google manage the purchase itself and the payment data; their retention periods apply.

8. Children

Perlina is intended for parents. Information about children that you enter (first names, form of address, tooth diary, photos, dentist appointments) stays on your device or in the backups you create yourself. We do not receive it.
