How A2Z Calculator handles permissions, app data, and your privacy.
A2Z Calculator only requests the device permissions it needs to power its features, such as storage access for saving or exporting your calculations. Your inputs and results remain your responsibility, and we use them only to provide calculation, saving, exporting, and syncing features.
A2Z Calculator asks for device permissions only when they're required for a specific feature. You can allow, deny, or change any of these permissions at any time from your device settings.
Storage access lets you save calculation history, export results as PDF or image, and manage files on your device. The app only accesses the files needed for the action you select.
Internet access may be used for app updates, optional cloud backup of saved calculations, showing ads in the free version, and customer support. Core calculators work fully offline.
We may process saved calculation inputs and results (only if you choose to save or sync them), basic device diagnostics, and general usage information to keep A2Z Calculator reliable and to improve performance.
A2Z Calculator may rely on trusted third-party providers for hosting, analytics, crash reporting, cloud storage, or advertising. These providers handle data according to their own privacy practices.
We do not sell your personal data or saved calculations. Data is only shared when necessary to provide app features, comply with legal obligations, prevent misuse, or complete an action you've requested.
We apply reasonable technical and organizational safeguards to protect app data. You're also responsible for securing your own device, account credentials, exported files, and any cloud storage you connect.
A2Z Calculator is designed to provide fast, reliable estimates for construction and engineering formulas. Results should be verified by a qualified professional before being used for structural, safety-critical, or regulatory purposes.
A2Z Calculator is not intended for use by children without guidance from a parent or guardian. We do not knowingly collect personal information from children without appropriate consent.
You can manage app permissions from your device settings, delete saved calculations or exported files from your device or cloud storage at any time, and choose when and with whom to share your results.
We may update this Privacy Policy as our features, legal requirements, or business practices change. Updates will be posted on this page along with the date they take effect.
If you have questions about this Privacy Policy or how your information is handled, reach out to us at hello@a2zcalculator.app.
