Your calculations. Your device.
Privacy Policy
CalcCanvas does not collect personal data through the app. It has no accounts, ads, analytics, tracking, or developer-operated cloud service.
What the app stores
Your canvases, numbers, formulas, notes, graphs, scenarios, and local recovery checkpoints are stored within the app’s storage on your device. Preferences such as language, onboarding status, and keypad layout are also stored locally.
Network access and sharing
The app’s calculation and storage features work offline. They do not send your canvas contents or usage information to the developer. When you export, print, or share a file, the data goes to the location, printer, app, or service you choose. Those destinations handle the data under their own policies.
Device backups and deletion
Device backup services may include app data according to your system settings. CalcCanvas does not provide automatic cross-device sync. You can delete canvases in the library. Local recovery copies can remain in the app’s checkpoint storage until removed or the app is deleted. Deleting the app removes app-controlled local storage, subject to operating-system backup and restore behavior. Deleting the app does not remove copies you exported or shared elsewhere.
Support and this website
If you email support, we receive your email address, message, and any attachments you choose to send, and use them to respond to your request. Do not include information you do not want to share. Support correspondence is separate from the app, which does not automatically send diagnostic reports to us.
These public pages are hosted on GitHub Pages. GitHub may process technical request information when you visit them under GitHub’s Privacy Statement. These pages have no added analytics or advertising scripts. Apple separately handles App Store and TestFlight services under its own privacy terms and your settings.
Changes and contact
This policy will be updated if the app’s data practices change. For privacy questions or support requests, email info@sdilejslunce.cz.
