Private photo storage needs a restore test before it receives irreplaceable pictures. If Stingle is on your shortlist, assess encryption, device compatibility, and recovery using a disposable album.
Upload photos and videos with different sizes and metadata. Check thumbnails, search or organization, sharing, and whether original files download unchanged. Move to another device and verify that account recovery works without exposing secrets to a helper. Read Stingle's published information on its security model and backup options; confirm the current client versions you intend to use.
Compare upload time, local storage usage, and what happens offline. Export an entire test album, compare checksums and metadata, then delete it and verify the deletion workflow. End-to-end encryption protects content in transit and at rest only if key management and recovery are understood by the people who depend on it.
