CalcLockAt a glance: Work from the source toward the destination: confirm the photo exists, check the picker and permissions, then test one import. Do not delete the app to refresh a selection list.
Find the source before changing settings
A photo that appears to be missing during import may still be safely stored in Photos. Start outside CalcLock: open Photos, locate the actual item, and view it at a useful size. If it is a video, play it. Note whether you are looking at your personal library, a shared collection, or a copy saved from a message. A preview inside another app does not establish that the item is in your Photos library.
Use a harmless, recently taken image as a control. If the control appears in the import picker but the intended image does not, investigate that source rather than treating the entire vault as broken. If neither appears, access settings or the selection interface deserve attention first.
Separate selection from ongoing access
Apple lets you review information access in Settings under Privacy & Security. Open Photos within those controls and inspect the entry for the relevant app if one is present. Read the choices actually offered on your iOS version. A selected-items permission can explain why one image is available while another is not.
An iOS selection sheet and a standing permission to browse the library are different mechanisms. Do not assume a missing Settings entry proves that importing is impossible. Return to the import flow and read its prompts. If you can choose the specific image there, try that narrow selection before granting broader access.
Retry one item, not the whole collection
Once the image is visible in its source location, attempt one import into the intended CalcLock vault. Enter that vault using its exact expression followed by two consecutive presses of equals. Check the destination before repeating the action: a slow response is not proof that the first attempt failed.
Open the result and inspect it. A selection highlight only shows what you asked to import; it is not a completion receipt. If there is an error, retain its wording and record whether the source was a photo, video, or file. You can describe this without attaching the private item or revealing your equation.
Keep troubleshooting reversible
Do not reinstall CalcLock, reset your phone, or delete the source just to make a picker refresh. The app has no export, backup, restore, or forgotten-equation recovery. Preserving the installation and independent originals matters more than quickly clearing an error.
After a successful import, review any permissions you expanded temporarily. Reducing future access does not erase a copy already imported. The vault copy and the Photos original now have separate lifecycles, so keep track of both rather than assuming a permission change moved or removed either one.
- Check the source item in Photos.
- Inspect the picker and the permission actually shown.
- Test a single harmless item.
- Verify the intended destination before retrying.
Questions, answered
Should I give full photo access to fix every import problem?
No. First confirm the source and try selecting only the needed item. Broader access cannot repair a missing source or guarantee that an import completed.
Will changing photo permissions delete my vault?
Photo permissions govern access to the Photos library. They should not be used as a deletion or recovery tool for files already imported into CalcLock.
