CalcLockAt a glance: CalcLock has no supported vault migration or restore route. Keep your originals outside the app and verify those files on a new phone before erasing the old device.
Treat migration as a verification task
Phone setup can look complete before every important file has been checked. Contacts may appear, the Home Screen may look familiar, and an app may download successfully while its collection still needs attention. The meaningful finish line is opening the right files on the new device, not reaching the end of the setup screens.
CalcLock uses exact equations to open separate device-only collections. It has no account, export, synchronization, backup, restore, or recovery feature. Its vault files are excluded from device backups and its access key is tied to the device. Quick Start or a fresh installation is not a supported route for moving these collections. Plan around independent originals, not a promise that the vault will migrate.
Before you begin: make a collection inventory
On the old phone, open each collection you intend to keep. Note an approximate item count and a few recognizable examples from the beginning, middle, and end. If several collections matter, check all of them rather than using one as a stand-in. Keep this inventory descriptive enough to help you verify the move without exposing private images or secret entry details.
Choose examples that reveal different kinds of problems: a fine-detail photo, an older image, and any other supported media types you actually use. Record any files already missing or unreadable so you do not mistakenly blame the migration. Check available space on the new phone and allow time for troubleshooting before handing over the old one.
Choose a supported route, then let it finish
Apple offers Quick Start, as well as transfer using an iCloud or computer backup. For wireless Quick Start, Apple instructs you to enable Wi-Fi and Bluetooth on the old device, place the new device nearby, and keep both powered and close together during migration. Downloading from iCloud can continue in the background; a direct device transfer requires waiting for completion before using the devices.
These iPhone migration methods do not provide a CalcLock migration path. For this app, move the independent originals you retained using a suitable file or photo transfer method, then verify those originals on the new device before importing fresh copies. If the vault contains your only copy, stop: the app has no export route to retrieve it for transfer. Keep the old device and installation rather than erasing them.
Check the new phone systematically
For CalcLock, first confirm that your independent originals are readable on the new phone. Import fresh copies into the collections you choose there. Enter the exact equation associated with a collection and press equals twice to reopen it. Matching the answer alone is not the same as entering the matching equation. This is a fresh import from retained originals, not restoration of the old vault.
Compare the newly imported collection with your source inventory. Open the selected examples at full size and inspect detail, orientation, and completeness. For videos, test playback as well. Close and reopen the app, then revisit the examples. Keep the originals outside the app even after the check passes, because the new collection still has no backup or recovery feature.
- Check every collection you intended to move.
- Compare counts where the app provides them, then check representative files.
- Confirm that recent imports and older files are both present.
- Keep the old phone unchanged while investigating any discrepancy.
Plan for a trade-in deadline
Suppose your new phone arrives on Friday and the return kit is due on Monday. Do the collection inventory before Friday, not while standing at the shipping counter. If you cannot verify a migration route, resolve that before the return window becomes pressure to erase your only accessible copy.
A family member's spare phone, a shared computer, or a borrowed cloud account may seem like a convenient temporary destination. Each introduces another access boundary. Use only storage you are comfortable entrusting with the material, and keep track of any temporary exported copies so that cleanup is deliberate rather than accidental.
The final check before erasing
Erase the old phone only after your independent originals and new imports meet your needs. If any wanted file exists only inside the old CalcLock installation, keep that phone: there is no export, migration, or recovery path for that file. A factory reset cannot be undone by downloading the app again.
- The intended collections open on the new phone.
- Representative files are complete and readable.
- Missing or mismatched items have been resolved.
- A recovery copy exists if the photos are irreplaceable.
- Temporary exports have known locations and appropriate access.
- The old device is no longer the only place the files can be opened.
Questions, answered
Will Quick Start transfer CalcLock automatically?
There is no supported CalcLock migration through Quick Start. Vault files are excluded from device backups and the access key is device-bound. Move your retained originals and import fresh copies on the new phone.
Can I verify a move just by comparing item counts?
No. Matching counts are useful, but they do not prove that each file is complete or usable. Open representative files, including important exceptions and recent additions.
What if my old phone has already been erased?
Look for independent originals in Photos, Files, or archives you made earlier. CalcLock cannot restore the old collections from a device backup, and reinstalling does not recreate them.
