I’m looking for a pragmatic way to switch to GrapheneOS from my current Android OS. I’ve installed quite a few speciality apps on Android that I would like to find an easier way to install on Graphene. Is there an app to aid the transition? It would first catalog all of the apps installed on Android, then even if it is one at a time, it provides a URL or method to install the app on Graphine. There is the matter of the app data and app permissions too. What are my options?
The short answer is: there’s no dependable one-click migration app that transfers an arbitrary Android installation—including apps, private app data, and permissions—to GrapheneOS. Android’s sandbox intentionally prevents that.
The pragmatic approach is to separate the job into:
- Cataloging and reinstalling apps.
- Migrating each app’s data through its supported export, sync, or transfer feature.
- Re-granting permissions deliberately.
Best low-friction approach
Before installing GrapheneOS, catalog your current apps with one of these:
- AppListBackup on F-Droid exports HTML, Markdown, or CSV with app names, versions, and package names.
- App List Export on Google Play can include each app’s package name and Google Play URL.
- If you are comfortable with a computer and ADB, this produces an authoritative list of third-party package IDs:
adb shell pm list packages -3 -i
Android officially documents the -3 third-party-app and -i installer filters in its ADB package-manager documentation.
A catalog app is close to the tool you described: it gives you a checklist and links. It generally won’t install everything automatically or carry over private data.
Reinstalling on GrapheneOS
For the simplest transition, install sandboxed Google Play from GrapheneOS’s preinstalled App Store, sign into the same Google account, and reinstall your apps from the Play Store. This is the authentic Google Play Store running as an ordinary sandboxed application—not a substitute store with privileged OS access.
This is usually the best source for:
- Paid applications and previous purchases
- Banking and financial applications
- Apps using license verification or in-app purchases
- Apps using Play Asset/Feature Delivery
- Apps that require Google Play services or push notifications
GrapheneOS says this provides near-complete Play ecosystem compatibility and recommends Play Store as the most secure way to obtain and update Play-distributed apps. Google Play can be confined to a particular user profile if desired. See the official sandboxed Google Play guide.
For apps not obtained from Google Play:
- Use F-Droid for applications actually distributed there.
- Use the developer’s official site or repository.
- Obtainium can track and install releases from supported developer repositories, but it is more useful for maintaining a curated set of direct-download apps than automatically discovering the provenance of every old app.
- Avoid random APK mirror sites.
I would not make Aurora Store the default migration method. It can be useful in specific cases, but official Play is better for paid apps, licensing, split packages, asset delivery, and authenticity.
What happens to app data?
This is the difficult part. Installing an APK is not the same as transferring its data.
Use, in descending order of preference:
- The app’s direct device-to-device transfer
- The app’s account-based encrypted sync
- The app’s built-in export/backup and import/restore
- Exporting ordinary user files to a computer or USB drive
- Starting fresh
Common categories to check individually:
- Password manager: confirm that the vault is synchronized or export an encrypted backup.
- Authenticator/2FA apps: export or transfer tokens and save recovery codes before wiping anything.
- Passkeys: verify where they are stored and whether they sync; some are tied to a Google password manager or vendor service.
- Signal, WhatsApp, and other messengers: use their own documented transfer or backup procedures.
- Notes, finance, health, automation, and specialty apps: look for Export, Backup, Sync, Database, or Transfer in each app.
- Photos and documents: copy them by USB, external storage, or your chosen synchronization service.
- Contacts: synchronize them or export a
.vcf. - SMS/MMS and call history: use a dedicated exporter compatible with both phones.
Android normally prevents one app from reading another app’s private storage. Modern Android has also made generic ADB backup largely obsolete, and many apps explicitly disallow backup. Banking apps, DRM apps, authenticators, and apps using hardware-backed keys may require fresh enrollment even when some data can be copied.
GrapheneOS’s built-in Seedvault backup is more relevant for later GrapheneOS-to-GrapheneOS migrations. It is not a universal importer for an existing stock Android phone, and app developers can still make their data non-restorable.
What happens to permissions?
Permissions generally should—and often must—be granted again. A catalog or APK transfer cannot reliably carry them over.
That is beneficial during this transition: start each app with no optional permissions and grant only what it needs. GrapheneOS also adds controls such as:
- Network permission
- Sensors permission
- Storage Scopes
- Contact Scopes
- Per-profile isolation
The old permission configuration may not map cleanly to these controls. Restoring permissions wholesale could also grant a newly installed version access you no longer intend.
Compatibility concerns
Most regular Android apps work, especially with sandboxed Google Play. The main exceptions are apps that deliberately require a Google-certified OS through Play Integrity, plus certain payment, banking, DRM, or corporate-management applications. GrapheneOS documents this limitation in its app and banking compatibility guidance.
Before wiping your old installation, test your indispensable specialty apps if you have access to a second supported Pixel. Pay special attention to:
- Banking and government identity apps
- Google Wallet/contactless payment
- Work-device-management and corporate VPN apps
- Medical-device companion apps
- Automotive apps and digital car keys
- DRM-heavy streaming apps
- Hardware-security-key and passkey workflows
A migration plan I’d actually use
- Export an app catalog containing names, package IDs, and Play links.
- Mark every app as critical, useful, or skip.
- Beside each critical app, record its data-transfer method and account credentials.
- Export authenticators, recovery codes, password vaults, messenger histories, contacts, SMS, and user files.
- Keep the old phone untouched—or make two independent backup copies—until the new setup is verified.
- Install GrapheneOS and lock the bootloader as instructed.
- Install sandboxed Google Play in the profile where compatible apps will live.
- Work down the catalog, installing from Play, F-Droid, or the developer’s official source.
- Restore each app through its supported mechanism and grant permissions anew.
- Test critical apps, notifications, 2FA, calls, navigation, and banking before erasing or trading in the old phone.
If GrapheneOS will be installed on the same phone you currently use, installation and bootloader operations wipe its data. In that situation, the backups must exist somewhere else and be tested before beginning.
