Privacy Policy
RetroFX collects nothing. There is no account, no sign-in, and no analytics. Nothing you type into the calculator leaves your device.
Last updated 5 August 2026
Who this covers
This policy covers the mobile application RetroFX — 3D Scientific Calculator (the “App”) for iOS and Android, published by Voidware Limited, a company registered in England and Wales (“we”, “us”). We are the data controller for the purposes of the UK GDPR.
What we collect
Nothing. The App does not collect, store, transmit or share any personal data or any other information about you or your device.
In particular, and to be explicit about the categories app stores ask us to declare:
- No name, email address, or any other contact detail
- No account, login, registration or password — there is nothing to sign in to
- No location data, precise or approximate
- No device identifiers, advertising ID, or IP address logging
- No usage or behavioural analytics, and no crash-reporting SDK
- No contacts, photos, files, microphone or camera access
- No advertising, and no advertising networks
- No cookies or similar tracking technologies
The App works entirely offline. Your calculations, and the settings you choose for brightness, display glow and volume, are held on your own device and are never sent anywhere.
Third parties
The App contains no third-party analytics, advertising or tracking libraries, and it makes no network requests of its own. Because we receive no data, we have none to sell, share or disclose to anyone.
The one thing outside our control is the store you installed from. Google Play and the Apple App Store handle the download, any purchase and any crash reports you may have opted into at the operating-system level, under their own privacy policies rather than this one. We see only anonymous, aggregate figures such as install and rating counts, and cannot identify you from them.
Your rights, and children
- Can I ask for my data, or ask you to delete it?
- You can ask, but we hold no data about you, so there is nothing for us to send you, correct or erase. Deleting the App removes its settings from your device. If you have written to us by email, see below.
- What about children?
- The App is suitable for all ages and does not knowingly collect data from anyone, children included. Since no data is collected at all, no data can be collected from a child.
- Where is data processed?
- Nowhere. No data is transferred, so no international transfer takes place. Voidware Limited operates from the United Kingdom.
- What if I email you?
- If you contact us for support, we hold your message and email address only for as long as it takes to answer you, and we use it for nothing else. Ask us and we will delete it.
Changes, and contact
If the App ever changes so that this policy no longer describes it, we will post the new policy at this address and update the date at the top before releasing that version.
