Ridena is in a closed alpha test. This page describes what we know about you, why, and how to get rid of it.

You can write to us any time — we also answer GDPR requests by email (a copy of your data, correction, deletion).
| Data | Why | How long |
|---|---|---|
| The email and note from the alpha test application, and the sending IP address | So we can send you an invitation and arrange the testing. The IP address only protects the form against flooding. | Until the alpha test ends, or until you ask for deletion. |
| Account: email, password (stored only as an irreversible hash), nickname, optionally a name and profile photo | Signing in and your public profile. | Until you close your account. |
| Rides: the track (GPS points with times), statistics, total climbing, weather, your note and photos Photos are resized to 1600 px on your phone, and the EXIF data — including where they were taken — falls away with it, so only a location-free copy reaches the server. Ridena is a diary, not photo storage, so the originals stay on your device. |
Your ride diary. For rides marked public the content is available to anyone who knows the link. We offer the GPX track for download only where you have given explicit consent — a checkbox on a public ride that we leave unticked. Without it others can view the ride but not download the track. You can withdraw the consent any time. |
Until you delete the ride. |
| Feedback: the text, your account email, the app version and browser details | Fixing bugs and seeing who tested. | Until the alpha test ends. |
| Privacy zone: the home point and radius (if you set one in the app) | So a public ride link never shows the track from your front door — the start and end of the track inside the zone are hidden in public view. The coordinates stay on the server and are never sent back to the browser. | Until you clear the zone or delete your account. |
| Sign-in session (token) | So you don't have to sign in every time. | Until you sign out. |
Ridena uses no analytics, no ad systems and no tracking cookies. We have no Google Analytics and no social-network pixels.
Ridena stores no cookies in your browser. Neither our own nor third-party — verified across the whole site and the app. That's why you won't find a consent bar here: there is nothing we would need consent for. If we ever add analytics or anything not needed to run the app, we'll ask first.
The app does need a few things stored right on your device, otherwise it wouldn't work — you couldn't stay signed in, ride offline or keep a diary. None of it is used for tracking and none of it goes anywhere other than where you send it yourself. Here is the complete list:
| What | Where | What for | How long |
|---|---|---|---|
| Sign-in | localStorage | keeps you signed in so the app doesn't ask for a password every time | until you sign out |
| App settings map, language, units, route type, the profile window, radar on/off |
localStorage | remembers how you like the app set up | until you delete the data |
| A ride recording in progress | localStorage | if the system closes the app, the ride is restored with its kilometres when you reopen it | until the ride is saved or discarded |
| The loaded route and the plan in progress | localStorage | a route survives the tab being closed; we'll offer to finish a plan in progress | until replaced; a plan for a week at most |
| A ride diary with photos | IndexedDB | your rides — this is the heart of the app | until you delete the rides |
| Maps downloaded for offline use, cycle routes, elevations and surfaces | Cache Storage, IndexedDB | so you get there without a signal and the map isn't downloaded over and over | until you delete the data |
| Varia radar and sharing with a buddy the paired device, the sharing code, the phone's name |
localStorage | so the radar reconnects by itself when switched on and sharing works | until the radar or sharing is switched off |
| Your own keys and connections the map key — only if you enter one yourself |
localStorage | connections you asked for yourself | until disconnected |
How to get rid of it: everything is stored only on your device,
so it's enough to clear the site data in your browser ridena.cz
(in both Chrome and Safari it's called “clear site data” or “remove cookies
and website data”). The app then starts from scratch. Rides you uploaded to the server
won't disappear that way — delete those in the diary, or ask us to delete your account
at ahoj@ridena.cz.
We sell them to nobody. Running the service does need third parties, though — and they receive only what is necessary:
Just write to ahoj@ridena.cz. We can delete the whole account with all its rides and photos — just say the word.
The site runs only over an encrypted connection (HTTPS). Passwords are stored as an irreversible hash, so not even we can see them. Database credentials live outside the public part of the site.
Ridena is evolving, so this document will change. The date of the last update is at the top. We'll let registered users know about any substantial change by email.
