Privacy policy
Last updated 14 August 2026. This covers the Nexus application and the nexusmessenger.app website. It is deliberately short, because there is not much to declare.
What the application stores, and where
Every service you add gets its own storage partition: its cookies, its local storage, its local databases. That is exactly what lets two accounts of one service stay signed in side by side without signing each other out.
- This data is written to the application’s data folder under your Windows profile, and never leaves the machine.
- It holds whatever the service puts there: session tokens, and depending on the service, a local copy of your conversations.
- Removing a service in Nexus removes its partition, and with it that session and cache.
- Uninstalling Nexus removes the data folder.
What Nexus does not see
Your credentials are typed into each service’s official pages, not into any Nexus interface. The application does not modify those pages, injects no script, and does not sit between you and the service. No message and no password passes through us: there is no server-side “us”.
The only connection Nexus makes on its own
The application asks GitHub, where releases are published, whether an update exists. Like any request on the internet, that one exposes your IP address to the server contacted, here GitHub, whose privacy policy then applies.
Beyond that: no telemetry, no crash reporting, no usage statistics, no installation identifier.
The services you add
WhatsApp, Teams, Telegram, Gmail and the rest are loaded from their own servers, in their own official interface. They collect what they normally collect, and their policies apply in full, exactly as if you had opened them in a browser.
The nexusmessenger.app website
- No cookie is set, on any page.
- No analytics is active, and no third-party script is loaded.
- The /download address only resolves the current release and redirects you: the download itself happens on GitHub.
- The site is hosted on Vercel, which keeps technical logs like any host, including visitors’ IP addresses.
Your rights
We hold no data about you, so there is nothing on our side to access, correct, export or delete. For the data held by the services you use, contact them: they are the controllers. To erase what sits on your machine, remove the service inside Nexus, or uninstall the application.
Check rather than trust
Nexus is published under the MIT licence and its source is public. Everything above can be read in the repository, including the update request and the absence of any other outbound connection. A privacy policy is worth exactly as much as your ability to verify it.
Changes and contact
If this document changes, the date at the top changes with it, and the edit history stays visible in the site’s repository. For any question, open an issue on the GitHub repository.
