Privacy Policy — X-Calculator

Effective date: 19 September 2026

X-Calculator (“the app”, “we”, “us”), published by AiDigiApps, is a calculator app for iPhone and iPad. This policy explains what data the app handles — which is easy, because the app is built to handle none of yours.

In short: X-Calculator collects no data. There is no account, no sign-in, no analytics, no ads, no trackers — and no network code at all. Everything you calculate stays on your device.

Information the app handles

Calculations and history

Your calculations, and the optional calculation history, are stored locally on your device only. History recording can be turned off in Settings, and you can clear it or delete all app data at any time. When you use Share or Export, iOS's own share sheet opens and you choose where the data goes; the app does not transmit anything on its own.

Settings

Preferences such as theme, precision, rounding policy and currency are stored locally on your device and never leave it.

Network access

The app contains no networking code. It makes no requests to our servers or anyone else's. Links in Settings (Help Center, Privacy Policy, Terms of Use) open in your browser; email links open your mail app. Web-server logs on aidigiapps.com (such as IP address) may be recorded by the host as part of serving those pages in your browser; we do not use them to identify or track you.

Support email

If you contact us at support@aidigiapps.com — including via the app's “Send feedback” or “Report a bug” buttons, which simply open your own mail app — we receive whatever you choose to send. Bug reports include diagnostics (app version, iOS version, device model, locale and calculator settings) only if you leave the “Include diagnostics” toggle on, and you can see and edit the full email before sending it. We use support emails solely to help you and improve the app.

Analytics and advertising

The app includes no third-party analytics or advertising SDKs and does not track you across apps or websites.

Data sharing

We hold no data about you, so there is nothing to share or sell. Apple distributes the app under its own terms.

Data retention and deletion

All app data lives on your device. Deleting the app removes it completely, or use Settings → Delete all data inside the app. We hold no personal data about you on any server, so there is nothing for us to delete on our side.

Children

X-Calculator collects no personal information from anyone, including children.

Changes to this policy

We may update this policy; the “Effective date” above will change accordingly. Material changes will be reflected here.
