SNIZ is designed as a privacy-first application. All data you enter into the App is stored exclusively on your device in encrypted form. There is no automatic transmission to servers operated by the provider or to third parties.
Data is only transmitted when you actively use a specific feature (see section 4 "Feedback feature").
The following data may be entered into SNIZ — all entries are voluntary and stored only locally:
The local database is fully encrypted with SQLCipher using AES-256. The database key is bound to your device and stored in the operating system's secure key storage (Android Keystore / iOS Keychain).
Local processing is performed for the performance of the contract concluded by using the App (Art. 6(1)(b) GDPR). Since the data never leaves your device, the provider has no access to it at any time.
The App contains an optional feedback form within the settings screen. If you actively use this feature, the text you enter is transmitted to a server operated by the provider.
Without providing an e-mail address, the submission is fully anonymous.
Your IP address is processed only short-term in server memory for rate-limiting (max. 3 requests per hour) and is not permanently linked to your message.
Art. 6(1)(a) GDPR (consent by actively submitting) and Art. 6(1)(f) GDPR (legitimate interest in product improvement).
During onboarding, an optional free-text field is offered. If you enter text and leave the "Send as feedback to SNIZ" checkbox enabled, your input is transmitted anonymously (text + language setting only — no identifiers). You can opt out by unchecking the checkbox at any time.
Legal basis: Art. 6(1)(f) GDPR. As the data is fully anonymous, consent is not required.
PIN and PUK are stored exclusively as cryptographic hashes. Biometric data is processed solely by your device's operating system — the App only receives a success/failure confirmation.
SNIZ uses only local notifications. No push tokens are registered and no data beyond what is technically required is transmitted to third parties (Apple APN, Google FCM).
SNIZ contains no tracking libraries, no advertising, no web analytics tools and no third-party crash reporting that transmits personal data to external servers.
| Permission | Purpose | Required? |
|---|---|---|
| Notifications | Local reminders about expiring interest guarantees | Optional |
| Biometrics | Convenient unlocking of the App lock | Optional |
| Internet access | Solely for the feedback feature | Only when actively used |
The App does not request access to location, camera, microphone, contacts or calendar.
You also have the right to lodge a complaint with a supervisory authority — in particular the LDI NRW (Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen, Germany).
The current version is always available at sniz.app/privacy. Material changes will be communicated as part of an App update.
The following subsections apply exclusively to visiting this website at sniz.app — not to the App itself (see the preceding sections for that).
This website is hosted with a hosting provider in Germany. On every visit, the web server automatically processes technically necessary information transmitted by your browser: IP address, date and time of access, page requested, amount of data transferred, referrer URL, and browser type and operating system.
This data is used solely to ensure the security and stability of operations and is not combined with other data sources. Legal basis: Art. 6(1)(f) GDPR (legitimate interest in the secure and functional operation of the website).
The fonts used on this website (Google Fonts: Manrope, Sora) are served locally from our own server. There is no connection to Google's servers and no transmission of your IP address to any third party.
This website does not use cookies, analytics or marketing tools, or tracking pixels. No user profiles are created.
The website links to external services (e.g. Google Play, Apple App Store). Their own privacy policies apply to data processing on those external sites.
