Here’s my take on this.
Recovering deleted digital assets like Snapchat filters can be a tricky process. On one hand, some data might linger in your device’s cache. For Android, a deep dive into the app’s data folders with a file manager could potentially uncover residual files, though this is a technical route and isn’t guaranteed to work, as the cache is regularly cleared.
On the other hand, most recovery methods depend on having a system in place before the deletion occurs. For instance, monitoring tools typically log activity as it happens. If such a service was active, it might have a record of the filter being used, but it can’t retroactively retrieve the filter file itself. Requesting your data from Snapchat might give you a log of the filter’s name, but not the functional filter.
