How to make your iPhone photos more private
A practical starting point: hidden photos, device access, and the copies you might forget.

Hidden or encrypted: what is the difference?
Look beyond a lock screen and ask how a product actually protects your files.
Start with the situation you want to prevent
Keeping a photo out of a casual gallery view is different from protecting a stolen device or a copied backup. Define your concern first. A hidden folder, device authentication, file encryption, and an encrypted backup are separate controls that can work together.
A lock screen tells only part of the story
A PIN prompt shows that the interface checks access. By itself, it does not explain how files are stored. Equally, calling an album hidden does not mean the operating system provides no protection. Look for documented behavior instead of judging security by a product name or screenshot.
Ask about keys and recovery
Encryption transforms readable data using a key. Useful questions include where keys are created, who can access them, what reaches a server, and how recovery works. If a provider can restore everything after you forget every secret, understand what mechanism allows that. Convenience and recovery need an explicit design.
Evaluate evidence, not badges
A named algorithm is not a complete security review. Implementation, device access, backups, and update practices matter too. Prefer clear architecture documentation and review reports with a stated scope. SeraShield is researching a future vault, so the concept on this site should not be treated as an implemented or audited security product.
