Poltreder, private secure phot

We all love taking photos and videos with our mobile, but when the time comes to share them, it is often a real headache. Should we trust cloud providers to share personal photos with our friends regarding privacy issues? How to prevent my photos from being spread on social networks without my consent? Don't feel comfortable when sending my photos by email? Anyway, sending large videos by email is impossible.

Poltreder allows you to share your photos and videos without storing them in any cloud server to preserve your privacy. Sharing is secure and end-to-end encrypted between mobile terminals, and is done only from device to device (P2P) without any intermediate server. Only your friends have a copy of your photos and videos, but they cannot access them to save elsewhere (screenshot is also disabled). Your data privacy is the main concern of the Poltreder application. Imagine Poltreder as the Signal of Instagram!

All the functionalities in detail:
• Poltreder lets you manage and share all the photos and videos available in the library of your mobile device (i.e. taken with the mobile camera).
• Organize your photos and videos into collections. A collection is a simple tag (see it as a folder) to group your photos and videos. You can then share the collection with your friends. This allows you to control who can view which photos or videos of your camera library.
• Your photos and videos are not saved in any cloud server, but directly transferred towards the devices of your friends. Sharing with Poltreder is fully secure and encrypted.
• Whenever you delete a photo or video from a collection, it still exists in your device, but it is automatically removed from the devices of your friends. Similarly, when deleting photos and videos permanently from your device library, they are also removed from any collection which contains them, and mostly, as well as from the devices of your friends with whom you have shared them.
• If you decide to remove a friend from accessing a collection, the collection (incl. all the photos and videos) will be also deleted from your friend's device.
• If you delete a friend, all the collections, including photos and videos, you shared with your friend will be removed from his/her device, and in turn, all the photos and videos shared by your friend will be also removed from your device.
• No need to create an account to use Poltreder. We just ask you to choose a username and an avatar: this only allows your friends to identify you easily! Account creation is done locally on your device using a process of invitations by email to link accounts between them for sharing photos and videos.
