Décodeur ANEF naturalisation, from naturalisation-facile.fr, decodes the ANEF portal's technical replies so applicants can track French naturalization progress. The extension intercepts API responses and translates over sixty internal status codes into readable French, showing sub-statuses like CAA and CAE plus estimated processing dates. It embeds a simplified tracking dashboard in the official ANEF pages and processes data locally, giving foreign applicants clearer milestones and less administrative uncertainty.

What the extension reveals about an application timeline

The extension intercepts and interprets the ANEF portal's technical responses, translating more than sixty internal status codes into plain French and exposing sub-statuses such as CAA (Contrôle À Affecter) and CAE (Contrôle À Effectuer). It also surfaces estimated processing times and key dates tied to each stage, and it places a simplified tracking dashboard inside the official ANEF view so applicants can see milestones alongside the portal's native file display.

How the tool treats personal data and privacy

Privacy behavior is explicit: the code is open-source and the extension performs decoding inside the user's browser, so personal application data does not get transmitted to external servers. The developer states the tool operates locally to interpret API replies, and the project is independent from the ministry, meaning the overlay is an unofficial, community-driven interpretation rather than a government service.

How actionable and reliable the decoded statuses are

The mapping covers a wide set of internal responses and pairs sub-status labels with estimated times and milestone dates, which makes the raw API responses more actionable for applicants. The extension is highly regarded by the applicant community for reducing uncertainty, a reception that indicates the mappings address a real information gap in the naturalization workflow rather than adding speculative commentary.

Integration, compatibility, and configuration friction

Installation is the usual browser-extension flow: it runs on Firefox for desktop and Android and can be used on iOS via browsers that support web extensions such as Orion. Because decoding happens locally in the browser, no external account creation or file uploads are required. The overlay requires a compatible browser, so applicants using other browsers cannot use the integrated dashboard without switching to a supported one.

A practical, privacy-aware tool for applicants seeking clearer milestones

The extension is a pragmatic option for foreign nationals who need clearer visibility into their ANEF application timeline. One notable limitation is its dependence on ANEF's raw API responses, so changes to those outputs can temporarily break or alter the translation mapping. For applicants tracking a file, the extension offers a privacy-conscious way to reduce procedural uncertainty while remaining cautious about interpretation limits.
