Privacy policy
Last updated: 22 September 2026. The Spanish version of this policy (Política de privacidad) is the reference text.
PilotKeys is a free study tool. It is designed to work without asking you for any data: there is no sign-up and there are no forms.
1. Controller
The controller is the owner of PilotKeys, a personal, independent project. For any enquiry or to exercise your rights, write to pilotkeys.web@gmail.com.
2. The calculator: your calculations never leave your device
Everything you type into the calculator is processed in your own browser. It is not sent to any server and we neither see it nor store it.
Your browser stores only your practice preferences («Exam mode», «Study helper» and «Use keyboard») to remember them on your next visit. They are not cookies, they do not identify you, and you can delete them from your browser settings.
3. Visit statistics
We currently use no visit-statistics tool. If we add one in future, it will be a cookie-free tool giving aggregate figures only, and we will state it here.
4. Advertising (Google AdSense)
This site is funded by Google AdSense ads. Google and its partners use third-party advertising cookies to show and measure ads and, if you accept, personalise them. Consent is managed through the Google message shown when you arrive. More information in our cookie policy and at https://policies.google.com/technologies/ads.
5. Other services
Fonts are loaded from Google Fonts; when they are downloaded Google receives your IP address, as with any web resource. The site is hosted by Hostinger, which keeps the usual technical server logs.
6. Your rights
Although this site asks you for no data, you can exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to the contact email. If you think we have not handled your request properly, you can complain to the Spanish Data Protection Agency (www.aepd.es).
