NullVault on iPhone and Android
On both platforms, you can create and unlock vaults and import and view local content offline without a NullVault account. Files must already be available on the device; downloading a cloud-only original still needs a connection.
See offline use without an account, NullVault for iPhone, and NullVault for Android for the local-use boundary and platform-specific online services.
What the claim should mean in practice
An offline, no-account vault should let you create and open local storage without ever signing in to anything. That is a testable claim, but a minimal functional smoke test does not establish every network or recovery behavior.
Install it, decline any sign-in, and see whether you can create a vault and import a file. If you cannot, the description was aspirational.
Optional network access is normal
Very few apps are entirely network-free, and that is not automatically a problem. Update checks, purchase validation, and optional backup features all legitimately use the network.
What matters is whether those are optional and separable from local use. A vault whose core function works offline, with cloud features you can leave disabled, is behaving as advertised.
Offline is not anonymous
No account removes a provider relationship. It does not remove the platform's record that you installed the app, the store's purchase history, operating-system telemetry, or the device's own exposure.
Conflating the two leads people to skip precautions that still apply, which is worse than not having made the choice at all.
Verify rather than trust
- Create and open a test vault without signing in to anything.
- Observe which features prompt for network access, and whether they are optional.
- Create a portable encrypted backup and restore it.
- Understand how updates and purchases work, since those are the usual network dependencies.
The two errors
- Equating offline with anonymous or untraceable.
- Keeping the only copy on one phone because the storage is encrypted.
A fictional example
Leo starts with a non-sensitive test: “Create and open a test vault without signing in.” Next, Leo follows the second check: “Observe which features require network access.” This fictional scenario demonstrates the decision process; it is not a report of product testing.
Common mistakes
- Equating offline with anonymous
- Keeping the only copy on one phone
What this workflow does not change
- Equating offline with anonymous
- Keeping the only copy on one phone
Questions people ask
Does NullVault require an account on iPhone or Android?
No. On both platforms, creating and unlocking vaults and importing and viewing local content work offline without a NullVault account.
Which operations need an internet connection?
App updates, store purchases and restoration, and optional online backup or sharing need their relevant platform services and a connection. iPhone iCloud backup and sharing use Apple services; these are separate from core local vault use.
Does importing into an offline vault remove other copies?
No. Originals, exports, synchronized photo libraries and backups can remain outside the vault. Review those copies separately before deleting anything.
Does offline use replace a backup?
No. Losing the device, deleting the app or losing your recovery credential can make local content unavailable. Keep and test an appropriate encrypted backup and recovery path.
