OpenTregna is an independent app.
OpenTregna is not affiliated with, endorsed by, or representative of any government authority, wilaya, municipality, transport directorate, public transport operator, or official public body. OpenTregna does not represent the Algerian government and does not provide a government service.
OpenTregna displays practical and indicative urban mobility information, including available lines, stops, possible connections, map references, and calculated route suggestions.
The information is provided to help users plan trips, but it may be incomplete, experimental, outdated, or contain errors. For official, regulatory, fare, contractual, or guaranteed transport information, users should consult the relevant transport authorities or operators directly.
OpenTregna data is built from independent mapping work, field checks, moderated user contributions, publicly available references, and community feedback. User-submitted corrections are reviewed before being used to improve the public dataset.
When an official or public operator source is available for a city or network, it may be consulted as a reference. OpenTregna does not claim that every displayed route, stop, or itinerary is copied from or guaranteed by an official source.
The following links are examples of official or public references that may be consulted where relevant. They are provided for transparency and do not imply affiliation, endorsement, or real-time data sharing with OpenTregna.
The map background and base geographic data are provided through OpenStreetMap-compatible mapping sources.
Users may suggest a line, report a missing stop, place a point on the map, or report an error. Contributions are reviewed before being used to update the information shown in the app.
