Cookie Policy
Last updated: 20 October 2026
This policy explains what cookies and similar technologies Tachyo uses, as required by the Privacy and Electronic Communications Regulations (PECR). It should be read with our Privacy Policy.
1. What this covers
Cookies are small files a website stores on your device. Similar technologies, such as your browser’s local storage, work in much the same way. PECR requires consent for most of them, but not for those that are strictly necessary to provide a service you asked for.
2. This website (tachyo.co.uk)
- We do not set advertising, analytics, social-media or other tracking cookies on this website, so there is no cookie banner to accept or reject.
- The contact form and pricing calculator do not use cookies. The pricing calculator’s fleet-size figure is kept only in the page while you use it.
- Typefaces are delivered from our own servers, not from a third party.
- Our hosting provider keeps standard server logs (IP address, browser type and the pages requested) for security and to run the service, as described in the Privacy Policy.
If we add analytics or other non-essential cookies in future, we will ask for your consent first and update this policy.
3. The admin dashboard (app.tachyo.co.uk)
When you sign in, the dashboard stores the following in your browser’s local storage. These are strictly necessary for the service you asked for, or are settings you chose, so no consent is needed:
- your sign-in session (a token issued by our authentication provider) so you stay signed in;
- a flag and your role, used to show the right screens after sign-in (access is still enforced on the server);
- your email address, only if you tick “remember me” on the sign-in screen;
- which alerts you have cleared; and
- your alert-sound preferences.
None of these is used for advertising or to track you across other sites.
4. The driver app
The Tachyo Driver app stores your sign-in session and settings on your phone so you stay signed in and the app works. It does not contain advertising identifiers or third-party analytics or advertising software.
5. Third-party resources
The dashboard and the driver app load a few resources directly from third parties, such as map tiles and typefaces. They do not set cookies for us, but they receive your IP address when they are loaded:
- OpenFreeMap / OpenStreetMap contributors — Map tiles and map styles for the live map and journey history in the dashboard, and the map in the driver app. Data involved: IP address and the map area being viewed. Driver identities are not sent.
- OpenStreetMap Foundation (Nominatim and embedded map) — Address look-up when an administrator uses a location to fill in an address, and the map preview shown when an administrator compares a fuel receipt's recorded location. Data involved: IP address and the coordinates being looked up or displayed.
- Google Fonts (Google LLC) — Delivers the typefaces used by the admin dashboard. Data involved: IP address and browser details of the person loading the dashboard.
6. Your choices
You can clear local storage and cookies at any time in your browser settings; signing out of the dashboard also removes your session. If you clear them you will have to sign in again. Questions: privacy@tachyo.co.uk.
