Mango's source code is licensed under GPL-3.0 (see LICENSE). That license
already grants you the right to run, study, modify, and share the software
for any purpose, and by design it cannot be narrowed by a side document like
this one. Nothing here removes or limits any right the GPL gives you over
the code itself.
What this document does cover is narrower: the project's own stated purpose, and the rules for using spaces the maintainers run, such as the issue tracker, discussions, and any official builds or website. Think of it as "what we're building this for and what we'll help with," not "what you're legally permitted to compile and run."
Mango exists to let people run 32-bit-only (armeabi-v7a) Android apps they already legitimately own on newer 64-bit-only (arm64-v8a) hardware, in cases such as:
- The app was abandoned by its developer and never received a 64-bit build.
- The developer no longer exists, or the app is no longer maintained in any form, but the app itself still works fine otherwise.
- Niche or special-case hardware/firmware combinations where no 32-bit compatibility layer is available at all.
This mirrors what Tango (Amanieu Systems) already does at the OEM/ROM level for a handful of devices. Mango is an independent, from-scratch project and has no affiliation with Amanieu Systems or Tango, and does not use or contain any of their code.
Mango is not intended, designed, or maintained to help anyone bypass purchase requirements, license checks, DRM, subscription paywalls, or any other access control that an app or its developer puts in place. Using Mango, or any patch, plugin, or fork of it, for that purpose falls outside the project's intended use.
In practice this means:
- The maintainers will not knowingly accept, review, or merge contributions whose primary purpose is defeating license verification, purchase checks, or similar restrictions.
- Issues or discussions asking for help with that kind of use may be closed without a detailed response.
- This is a statement of project intent and community norms, not a technical restriction. Mango cannot inspect what any given user does with it, and the GPL does not allow the software itself to enforce this.
If you use Mango:
- You're responsible for complying with the law in your jurisdiction, including copyright law, and with the terms of service of any app you patch.
- You're responsible for only patching APKs you're legitimately entitled to run.
- Rooting a device and patching system-adjacent files carries real risk,
up to and including a bricked device or a broken app. You take that risk
on yourself; see
LICENSEsections 15-16 for the underlying "no warranty" terms. - Mango is not a replacement for judgment. If an app's own terms forbid reverse engineering or modification, patching it may put you in breach of that agreement even where copyright law itself would allow it.
Mango is a community passion project, not a commercial product, and it
makes no promise that any given app will work after patching, or that
patching won't damage the app, your data, or your device. See LICENSE
for the full disclaimer that governs the software.
As the project and community grow, these terms may change. Material changes will be noted in the project's changelog.
Questions about these terms belong in a GitHub issue or discussion on the project repository.
