## Review summary

Top issues across reviews are reliability and maintenance: frequent crashes and the app not staying open, especially after iOS updates. The app appears unmaintained, with no recent updates and slow or no developer responses. Data access problems are common: passwords can be lost or unrecoverable, stored items can vanish after updates, and adding/importing photos or videos often fails. Basic navigation is limited (no folders or search). Payment problems persist (upgrades charged but not delivered) and support is slow or absent. A few reviews note the concept and even a free browser as positives, but reliability is the main concern.

### Pros

- Private vault concept for hiding photos/videos is appealing.
- Free browser and feature set described as mostly free.
- Initial functionality when first installed or purchased.

### Cons

- Frequent crashes and the app won’t stay open, especially after iOS updates.
- No recent updates; compatibility with newer iOS versions is poor and the developer is unresponsive.
- Password management issues (lost passwords; no reset option).
- Data access problems: items can vanish after updates and adding/importing photos/videos often fails.
- Payment issues: upgrades charged but not delivered, with slow or no support.
