 While it may be tempting to link your Signal account to your desktop device for convenience, keep in mind that this extends your trust to an additional and potentially less secure operating system.

-Signal takes security very seriously, however there is only so much an app can do to protect you.

-Molly offers two variants of the app: **Molly** and **Molly-FOSS**.
-
-The former is identical to Signal with the addition of Molly's improvements and security features. The latter, Molly-FOSS, removes Google's proprietary code, which is used for some key features (e.g., [FCM](https://en.wikipedia.org/wiki/Firebase_Cloud_Messaging) and Google Maps integration), in an effort to make it fully open-source.
-
-A comparison of the two versions is available in the [project's repository](https://github.com/mollyim/mollyim-android#readme).
-
-Both versions of Molly support [reproducible builds](https://github.com/mollyim/mollyim-android/tree/main/reproducible-builds), meaning it's possible to confirm that the compiled APKs match the source code.

 For the database encryption feature to be useful, two conditions must be met:
 
 1. Molly has to be locked at the time an attacker gains access to the device. This can include a physical attack in which the attacker seizes your device and manages to unlock the device itself, or a remote attack, in which the device is compromised and manages to elevate privileges to root.

-
-- Molly removes Signal's MobileCoin integration.
-- Molly is updated every two weeks to include the latest features and bug fixes from Signal. The exception is security issues, which are patched as soon as possible. That said, you should be aware that there might be a slight delay compared to upstream.
-- By using Molly, you are extending your trust to another party, as you now need to trust the Signal team, as well as the Molly team.

That said, you should be aware that there might be a slight delay compared to upstream, which may affect actions such as [migrating from Signal to Molly](https://github.com/mollyim/mollyim-android/wiki/Migrating-From-Signal#migrating-from-signal).
+
+Note that you are trusting multiple parties by using Molly, as you now need to trust the Signal team *and* the Molly team to deliver safe and timely updates.
+
+There is a version of Molly called **Molly-FOSS** which removes proprietary code like the Google services used by both Signal and Molly, at the expense of some features like push notifications. There is also a version called [**Molly-UP**](https://github.com/mollyim/mollyim-android#unifiedpush) which is based on Molly-FOSS and adds back support for push notifications with UnifiedPush, but it requires self-hosting a program on a separate computer to function. All three versions of Molly provide the same security improvements.

 [^2]: Future Secrecy (or Post-Compromise Security) is a feature where an attacker is prevented from decrypting **future** messages after compromising a private key, unless they compromise more session keys in the future as well. This effectively forces the attacker to intercept all communication between parties, since they lose access as soon as a key exchange occurs that is not intercepted.
