Privacy policy
In short: the app collects no data, contains no networking code and requests no permissions. This website sets no cookies, tracks nothing and loads nothing from third parties. There is therefore nothing we could analyse, store or pass on.
1. Who is responsible
Blaser Connections, Romanshorn (Switzerland). Contact for any privacy question: info@jebla.ch.
2. The app: which data is processed
None. That is not a promise but a property of the program:
- The app's manifest declares not a single permission — in particular no internet permission.
- There is no code path that opens a network connection. The app is technically unable to transmit data.
- No analytics, advertising or crash-reporting library is bundled.
- The Play entry accordingly declares “no data collected” and “no data shared”.
3. What is stored on the device
- History: the expressions you calculated, with result and timestamp, in a local database inside the app storage.
- Settings: separators, default VAT rate, appearance, haptics and start tab.
This data never leaves the device and is not accessible to us. It is deleted when you clear the history in the app, clear the app data or uninstall the app. No backup of this data takes place — including Android backups, which the app explicitly opts out of.
4. This website
- No cookies, no tracking storage. The only thing kept in local browser storage is your language choice (DE/EN) — a convenience setting, not measurable and not personal.
- No analytics. There is no measurement tool, no tracking pixel and no embedded third-party content.
- No external resources. Fonts, images and scripts are served exclusively from our own server, so opening the page contacts neither Google, nor Cloudflare, nor a CDN.
- Hosting logs: serving a web page inevitably produces access data at the hosting provider (Microsoft Azure Static Web Apps, West Europe region) — IP address, time, requested file, user agent. These logs are used to operate the site and to fend off attacks; they are not joined with other data and not used to analyse visitor behaviour.
- No contact form. To reach us, use e-mail; the terms of your mail provider apply.
5. Downloading through Google Play
The distribution channel for the app is Google Play. When you open the Play entry, download or update the app, Google processes its own data — we have no influence over that. Google's privacy terms apply.
6. Your rights
You have the right to information, correction, deletion and restriction of processing, and the right to complain to a supervisory authority. Since we receive no personal data about the use of the app or the website, information and deletion requests will normally come up empty — there is nothing we could hand out or delete. The history exists only on your device.
7. Changes to this policy
If the app or the website changes, this page is updated. The version in force is always the one at this address.
