If you still believe your snaps will self-destruct, you might want to review Snapchat's newest policy changes, as the company can now potentially keep your photos forever and share them. Oh, and by using the app, you grant Snapchat the rights to your photos.
After reminding users that recipients can find ways to save snaps, the company mentioned its own message deletion policy: "We can't guarantee that messages and corresponding metadata will be deleted within a specific timeframe."
New Snapchat ToS
Snapchat's former ToS had a different take on the word "store." In fact, Snapchat claimed snaps were deleted from company servers once the snap was opened by recipients, or if they went unopened for 30 days. It also claimed to delete snaps from recipients' devices. It's important to note that although Snapchat built up its business on disappearing snap claims, the company settled charges with the FTC because it deceived users. The FTC found that "promises of disappearing messages were false."
Regarding the new ToS, you alone "remain responsible for the content you create, post, store, or send," but Snapchat can profit from your content. By using the app, you "grant Snapchat a worldwide, perpetual, royalty-free, sublicensable, and transferable license to host, store, use, display, reproduce, modify, adapt, edit, publish, create derivative works from, publicly perform, broadcast, distribute, syndicate, promote, exhibit, and publicly display that content in any form and in any and all media or distribution methods (now known or later developed)."
Additionally, "you also grant Snapchat and our business partners the unrestricted, worldwide, perpetual right and license to use your name, likeness, and voice in any and all media and distribution channels (now known or later developed) in connection with any Live Story or other crowd-sourced content you create, upload, post, send, or appear in. This means, among other things, that you will not be entitled to any compensation from Snapchat or our business partners if your name, likeness, or voice is conveyed through the Services."
If you are using Snapchat for sexting, then you might want to rethink that plan. It does seem doubtful, however, that anyone using Snapchat to share sexually explicit selfies would choose to submit the snaps to "Live Story." If you use Snapchat in general, you might want to ponder that choice in light of the new policy changes. The new privacy and ToS policies are a far cry from the initial app that became popular for its privacy-enhancing self-destruct feature.
