Privacy Policy
Last updated: 23 October 2026
This Privacy Policy describes how Percalo Calculator handles information. The app provides percentage, discount, VAT and ratio calculation tools, with calculations and recent history available directly on your device.
1. Information we collect
Percalo Calculator is designed to work entirely offline. The app does not require user registration and, according to the stated app functionality, does not collect names, email addresses, phone numbers, location data or other personal information. It does not include advertising or analytics tracking.
2. Calculations and local history
Numbers entered into the seven calculator tools are processed on your device. The app stores up to 50 recent calculations, grouped by day, so you can view and edit past results. Calculation data is not sent to our servers.
3. Saved preferences
Your decimal precision, numeric separators, VAT presets and other appearance preferences may be saved locally on your device. Percalo can follow your device’s light or dark theme.
4. Clipboard and sharing
When you tap to copy a result, the selected information is placed on your device clipboard. When you choose to share a calculation summary, the information is passed to the app or service you select. That destination may process shared information in accordance with its own privacy policy.
5. Internet and third-party services
The core calculator works without an internet connection. Based on the provided app description, the app does not use advertising or analytics SDKs. Device operating-system services and recipient applications used for optional sharing are separate from Percalo.
6. Data retention and deletion
Your recent calculations and settings are retained locally until removed using available app or device controls. Clearing the application’s storage generally removes locally stored calculation history and preferences. The app developer cannot retrieve this local data from your device.
7. Children’s privacy
Percalo Calculator is a general-purpose calculator. It is not designed to request personal information from children and does not knowingly collect such information.
8. Updates to this policy
We may update this Privacy Policy to reflect changes in functionality, legal requirements or privacy practices. The latest version will be published on this page with an updated date.
9. Contact and correspondence
