Naftavio Privacy Policy

Last updated: 13 November 2026

Naftavio is an app published by Elenia Concept. It compares fuel prices near you or along your route. This page explains what data the app uses, why, and what you can do about it.

In short: no account, no sign-up, no name, no email. Your location is used on your phone to find nearby stations and is never stored on Naftavio's servers. Your settings and favourites stay on your phone.

1. The data processed

Your location

  • What it is used for: finding stations around you, and calculating distances and the cost of a trip to the station.
  • Where it is processed: on your phone. To load stations, the app asks the Naftavio server for the prices of an area (a wide zone), not for your exact location.
  • When it is sent: only when you confirm a price or report that a fuel is out of stock while at the station. It is then sent once, to check that you are less than 500 m from the station. Only the distance is kept, never the place.
  • Your choice: you can refuse location access and choose a city instead. The app remains usable.

The phone's technical identifier

  • When the app is first launched, it creates a random, anonymous identifier. It does not contain your name, your phone number or your email, and it is not an account.
  • It is used to prevent abuse (for example, the same person confirming a price a hundred times) and to find your alerts.

Your price confirmations and reports

  • When you confirm a price, enter a different price or report that a fuel is out of stock, Elenia Concept keeps: the station, the fuel, the price entered, the distance to the station, the time and the technical identifier.
  • This information is used to show "Confirmed" to other drivers. It only counts towards what is displayed for 6 hours.

Your alerts

  • If you create an alert (price drop, back in stock), Elenia Concept keeps the station, the fuel, the threshold you chose and the technical identifier, so that you can be notified.
  • You can turn them off or delete them at any time in "My alerts".

What stays on your phone

Your settings (fuel, vehicle, theme, language, radius), your favourites, your cities, your home and your work are stored only on your phone. They are removed if you uninstall the app.

Address search and routes

  • When you search for a city or an address, the text you type is sent to the API Adresse (a French public service, data.gouv.fr) to find the place.
  • When you plan a trip, the starting point, stops and destination are sent to a route calculation service (OSRM) to draw the route.
  • These services receive your request and the IP address of your connection, like any website.

The map

The base map comes from OpenFreeMap (data © OpenStreetMap contributors). To display the map, your phone downloads map images of the area shown.

2. What Elenia Concept does not do

  • The app does not ask for your name, email or password.
  • Elenia Concept does not sell any data.
  • The app does not track your location in the background.
  • This version of the app does not show ads and offers no purchases.

3. Where the data is kept, and for how long

  • Hosting: Supabase (database) and Cloudflare (delivery of prices and of this website). These providers may process some data outside the European Union; any such transfer is then covered by the safeguards provided for by the GDPR (the European Commission's standard contractual clauses).
  • Retention: confirmations and reports are kept for no more than 12 months, for statistics and abuse prevention, and then deleted. Alerts are kept until you delete them, and are deleted if they have not been used for 12 months.

4. Your rights

You have the rights of access, rectification, erasure, objection and restriction provided for by the GDPR. Since Elenia Concept does not know who you are, the simplest option is to uninstall the app: your local data is erased and the identifier is never used again. Confirmations already sent are deleted at the end of their retention period.

Data controller: Elenia Concept, publisher of Naftavio. For any question, or to exercise your rights: [email protected].

You may also lodge a complaint with the data protection authority of your country (in France: the CNIL, www.cnil.fr).

5. Price data

Prices and out-of-stock information come from official sources (for France: prix-carburants.gouv.fr, Licence Ouverte v2.0). Station brands and the map come from OpenStreetMap (ODbL).

6. Children

The app is not intended for children and does not knowingly collect data about them.

7. Changes

If this policy changes (for example when ads or the "Ad-free" offer are introduced), this page will be updated and the change will be shown in the app.
