You don’t need to know to secure your email with FlowCrypt. Power users with an existing public key are also served. Whether you have struggled with other ways to encrypt email or you are trying email encryption for the first time, you will find this a very simple secure email solution thanks to PGP. PGP stands for Pretty Good Privacy it's the standard for secure email encryption. This Gmail end-to-end encryption app lets you encrypt Gmail messages anytime your email security and privacy matters, without having to think about it. Most email providers don't give you the level of privacy that we should expect. That is why we created the FlowCrypt app that lets you encrypt google email without needing to learn anything new. Email PGP encryption has been historically a very difficult area, which few people used because there was no easy PGP solution around. If you were asked for a Public Key or a PubKey so that others can encrypt messages for you, just install FlowCrypt and you will find your new Public Key in the settings. Also, file encryption is fully supported. To encrypt an attachment just open a compose screen, add the recipient's email, and attach a file. If they have encryption set up on their end, that's it - just send the encrypted email out. PGP or the OpenPGP is a standard for encrypted communication used by more than 10 million people. FlowCrypt is compatible with most OpenPGP software out there. Looking forward to your feedback! Email us at human@flowcrypt.com as we're improving the app every day.

Membr is your memory for people. You meet someone worth remembering — a colleague, a new client, a friend of a friend. Then life moves on, and by next week the name is gone. Membr makes sure it never is. Add anyone in seconds. Just a name is enough to start. Membr later nudges you to fill in the details that matter: how you met, what you talked about, the things you'd want to remember before you see them again. WHY YOU'LL LOVE IT • Add people fast — A name and a tap. Flesh out the rest whenever you have a moment. • Recall anyone — Forgot a name? Search by what you do remember: "tall guy with a beard from the conference." Membr finds them. • Meeting briefs — Before you see someone again, pull an instant refresher on who they are and what you last talked about. • Circles & Events — Group people by how they fit your life — Work, Gym, College — or by where you met them — a trip, a wedding, a conference. • Photo memory — Snap a photo and Membr describes the face so it sticks. • Gentle reminders — An end-of-day nudge to capture who you met before the details fade. Membr is private by design. Your people, your notes, your photos — they're yours. No ads. We don't sell your data. Remember everyone. Miss no one.
