What stays on your phone

No account is needed. Your places, drone settings and language are stored only on your phone (in the browser's storage) and are not sent to our server.

What is sent to the server, and why

• Place coordinates, rounded to about 100 m – to get the forecast and the drone zone map link for that place. The server passes them to weather data providers (e.g. Open-Meteo). Forecasts are cached briefly (up to 30 minutes) by coordinates, with no link to you.
• GPS interference reports (Pro only): the place's coordinates, the kind of interference, the time and a hashed tag of your Pro account, so that one pilot counts once. Reports are shown for 3 days and deleted after 4 days.
• Map: when you open the map, its images come from the OpenFreeMap servers (OpenStreetMap data) – your browser asks them directly. Searching places by name goes through our server to Open-Meteo, with no link to you.
• Satellite view: when you turn on the satellite view on the map, its images come from Esri through our server – Esri does not see your network address. Our server does not keep these images.
• Usage statistics – only daily totals (for example how many times the app was opened, in a browser or as an installed app, on a phone or a computer), with no user identifiers. The websites also use Cloudflare Web Analytics, which sets no cookies.
• Statistics of this website and dronams.lt – the course of each visit: which parts of the page were viewed and what was tapped (with the seconds since opening), where you came from (without the link's parameters), the language, the type of device and the country (taken from the network; the network address is not kept). The browser itself counts and adds which visit this is and how many days since the previous one. The visit's number is random, kept only in the browser's session storage and replaced after a 30-minute break, so visits are not joined together or linked to you. While the page is open, a short signal every 30 s lets us see how many people are looking at it right now. The course of visits is kept for 90 days, the totals for 400 days. With "Do Not Track" or Global Privacy Control on in your browser, these statistics are not sent. The app does not collect such statistics.

Pro subscription

• E-mail address – to send you a sign-in code or link (sent by an e-mail service provider) and to link your subscription.
• Payments are handled on the website by Stripe and in the apps by Google Play or Apple. We never receive card details; we keep only the subscription status, its end date and the payment provider's customer number.
• Sign-in cookie: one necessary cookie with the Pro sign-in token (Pro users only), so that Pro keeps working after app updates.
• List of phones: for each phone where Pro is on, a random number, the browser type, a shortened hashed network address and dates, so that a subscription bought on the website or in Google Play works on at most 3 phones. A signed-out phone's entry is deleted.
• Security log: date of sign-in attempts, the e-mail address (masked for addresses that are neither Pro nor testers), browser type and a shortened hashed network address. Kept for 7 days.

Protection against abuse

Request limits use hashed tags of the network address and the e-mail address, kept for up to 2 days.

Legal basis and your rights

We process data to run the app and to perform the subscription contract, and in our legitimate interest of protecting the service and improving the websites (their visit statistics). You can ask to see, correct or delete your data by writing to [email protected]. You can complain to the State Data Protection Inspectorate of Lithuania (vdai.lrv.lt).

Other

We do not sell data or use it for advertising. The app is meant for adult drone pilots. If this policy changes, the date at the top is updated. How the app may be used is set out in the terms of use.
