Fuelo shows fuel prices in Greece and offers tools such as a trip-cost calculator, price alerts, a fuel log, a garage and a station map, with free and paid plans. This page explains what data we handle, why, and how you can control it. It is a plain-language summary, not legal advice.
Fuelo is operated by [OPERATOR LEGAL NAME], [REGISTERED ADDRESS], Greece, ΑΦΜ [VAT NUMBER][, ΓΕΜΗ NUMBER]. That operator is the data controller for the personal data described here and can be reached at support@fuelo.gr for any data-protection matter. We have not appointed a Data Protection Officer; this is not required for a service of this size.
If you create an account you give us your email address, used to send a secure sign-in link. Optional data you choose to save (price alerts, fuel-log entries, saved cars, saved stations and settings) is stored against your account so it syncs across your devices. You may also optionally add your name, phone number and a home address: the name personalizes emails and receipts, and the address is geocoded (via OpenStreetMap's Nominatim service) to a location so we can suggest nearby prices when your device's own location is unavailable. None of these three fields are required, and none are shown to any other user. If you're on a paid plan and generate a developer API key, we store the key's hash and usage counts, never the key itself in reversible form. If you do not sign in, your alerts and fuel log stay only on your device and are never sent to us.
The map and the “cheapest near you” feature use your device location only when you allow it, and only in your browser to rank nearby stations. Your device location itself is not sent to our servers or stored; a home address you choose to save is handled as described above. When you type in the map's place search, that text is sent from your browser to OpenStreetMap's Nominatim service to look up coordinates.
Paid plans are billed through Stripe, our payment processor. We never see or store your card details; Stripe collects and handles them directly, and processes payment via card or Revolut Pay. We store your plan, subscription status and a Stripe customer reference so we can show your billing status and let you manage or cancel it. Stripe keeps its own records of transactions as required by financial and tax regulation, independent of Fuelo.
By default we use only essential, functional storage: your theme, language and cookie-notice choice, an authentication session when you're signed in, a short-lived cookie that binds a sign-in link to the browser that requested it, and, when you're signed out, your alerts and fuel log kept on your device rather than our servers. Only if you accept on the cookie notice do we additionally load PostHog, a product-analytics tool that measures how the site is used: it records page views and in-app events (such as which tools you open), together with coarse referrer, country, browser and device-type information, and it sets its own cookies to recognise a returning browser across visits. It does not track you across other sites. We use no advertising cookies and we don't sell or share your data with advertisers. You can withdraw or change this choice at any time from “Cookie settings” in the footer; while analytics is off, PostHog loads nothing and stores no cookies.
Ask Fuelo answers questions in natural language. When you send a question, its text is forwarded to a large-language model (currently Google's Gemini, accessed through Vercel's AI Gateway) to generate the reply. If your question is about your own data, a short summary of your fuel log or saved vehicles may be included in that request so the model can answer. This is processed only to produce your answer and, under the AI Gateway's terms, is not retained by the provider or used to train models. Ask Fuelo is metered per plan. The weekly insight and the per-prefecture summaries are generated the same way but use only aggregate, public price data, never anything about you.
You can optionally enable two-factor authentication (a time-based code from an authenticator app) on top of the sign-in link. The underlying secret is generated and managed by our authentication provider (Supabase Auth); we do not store or see it. Access within our database is restricted per-account by row-level security, so your data is only reachable by your own signed-in session (or, where necessary, by us for support and legal compliance).
If you enable price alerts we send them by email and, if you opt in, by browser push notification. If you're on a paid plan we also send a receipt when you're charged and a reminder a few days before your subscription renews. Sign-in links and these transactional emails are sent through our email provider (Resend); we don't send marketing email unless you separately opt into the weekly digest. You can remove alerts or turn off the digest at any time.
Accounts and saved application data are stored with our database and authentication provider, Supabase, in the EU (Paris region). Emails are sent through Resend. Payments are processed by Stripe. AI replies are generated via Vercel's AI Gateway using Google's Gemini model. If you accept analytics, usage data is processed by PostHog in the EU (its EU Cloud, hosted in Frankfurt). The site runs on hosting/infrastructure providers (Vercel) that see standard web request data (like IP address) needed to serve pages and prevent abuse; when you open the map, your browser also fetches map tiles from OpenFreeMap and geocoding from OpenStreetMap's Nominatim, which receive your IP address. These providers process data only on our behalf and as we instruct them, and some (such as Vercel, Stripe and Google) may process data outside the EEA under their own appropriate safeguards, including the European Commission's standard contractual clauses.
Regional prices come from the Greek Fuel Price Observatory (ΔΙ.Μ.Ε.Α., fuelprices.gr) and other publicly available bulletins. Station locations and details come from OpenStreetMap, an open, crowd-sourced map database. These are third-party sources; prices are indicative regional averages, not station-specific quotes, and station data quality reflects what's available on OpenStreetMap at the time.
We keep your account and saved data for as long as your account is active. If you delete your account, your data is deleted immediately from our live database (see “Your rights and choices” below); it may persist briefly in encrypted backups until those age out on our provider's normal backup rotation. Stripe retains its own transaction records for as long as it's legally required to, independent of your Fuelo account.
Fuelo is not directed at children, and we don't knowingly collect personal data from anyone under 16. If you believe a child has given us personal data, contact us and we'll remove it.
You can delete individual alerts, log entries, cars and saved stations at any time from within the app. From your account settings you can download a copy of everything we hold about you, or permanently delete your account and all associated data yourself, which also cancels any active subscription. If you're in the EU/EEA or UK, you also have the right to access, correct, restrict, or object to how we use your data, to data portability, and to withdraw consent where we rely on it; contact us for anything the self-service tools don't cover. You also have the right to lodge a complaint with your local data protection authority - in Greece, the Hellenic Data Protection Authority (dpa.gr).
We may update this policy from time to time; this page shows the date it was last updated (10 September 2026). Material changes will be reflected here.
