Privacy Policy

This privacy policy explains what personal data the iOS app "SurvKit" processes. It applies exclusively to the app itself.

SurvKit is built strictly according to privacy by design (Art. 25 GDPR): the app processes personal data exclusively locally on your device. There is no server, no account, no cloud, no telemetry and no analytics SDKs.

Controller

The controller within the meaning of the General Data Protection Regulation (GDPR) is the natural person publishing "SurvKit" as an independent developer:

  • Name: B. Neuhaus
  • Address: Allerstraße 26, 12049 Berlin, Germany
  • Email: survkit@borisniehaus.de

Full contact details can also be found in the imprint.

Data protection officer

"SurvKit" is published by a single person as an independent developer. A data protection officer is therefore not legally required and none has been appointed.

No account, no server, no transmission

SurvKit requires no registration and operates no backend. All data you enter is stored exclusively locally on your device and transmitted to no one:

  • Emergency profile (e.g. blood type, allergies, emergency contacts) - local, protected by iOS Data Protection
  • Document vault - local, encrypted with AES-256-GCM, key stored in the iOS keychain
  • Location & tracks - kept in memory, or stored locally when you start a recording
  • Supplies, notes, checklists, learning progress - local
  • Messenger messages - end-to-end encrypted (Curve25519 + ChaChaPoly), sent directly to a device within Bluetooth / Wi-Fi range, with no server in between

The legal basis for this purely local processing is the provision of the functions you request (Art. 6(1)(b) GDPR).

Internet connections only at your request

The app only connects to the internet when you actively trigger it. For technical reasons, the respective third party receives your IP address and a user agent:

  • Offline map packages (GitHub Releases): the requested file name; map data © OpenStreetMap (ODbL)
  • Wikipedia articles (Wikipedia REST API): the titles of the requested articles
  • Weather (Open-Meteo): rounded coordinates for the forecast
  • Food barcode lookup (OpenFoodFacts): the scanned barcode number
  • Local AI model (Hugging Face): one-time download of the model file
  • Vehicle manuals: opening the manufacturer portal you selected

We do not log these requests; no identifiers beyond what is technically necessary are transmitted. The legal basis is the provision of the function you explicitly requested (Art. 6(1)(b) GDPR). Downloaded content then works offline.

Permissions

SurvKit only requests system permissions (location, camera, microphone, notifications, local network / Bluetooth) when a feature needs them - such as the camera for the document scanner or location for the map and compass. Data from these permissions is processed exclusively locally and never transmitted. Notifications are purely local (e.g. expiry dates in your supplies) - there are no push servers.

Storage period and deletion

All data resides exclusively on your device and remains stored until you delete it in the app or uninstall the app. An encrypted export (backup) only happens when you trigger it yourself, and is stored wherever you choose to save it.

Your rights

You have the rights under Art. 15-21 GDPR (access, rectification, erasure, restriction, objection, data portability) as well as the right to lodge a complaint with a supervisory authority (Art. 77 GDPR). Since all data resides locally on your device, you can exercise access, rectification and erasure at any time directly in the app. For any questions, contact survkit@borisniehaus.de.

Apple as distribution platform

SurvKit is distributed via the Apple App Store. Obtaining the app through the store is subject to Apple's own data processing (e.g. in the context of your account and the download), is governed by Apple's privacy policy and is outside the controller's sphere of influence.

Cookies and tracking

SurvKit uses no cookies, performs no tracking and embeds no analytics, advertising or crash-reporting SDKs.
