Utilities apps and their data APIs
Scanner, translator and privacy tools — the OCR, conversion and file-handling endpoints behind everyday utilities.
The utilities category splits into two families: camera-to-PDF scanners with cloud backends, and personal vaults. The scanners — Simple Scan, Genius Scan and TapScanner — all pair the app with a cloud vault: feature flags and sync quotas (Simple Scan's PUT /v1/config/features), session bootstrap and vault item lists (Genius Scan's GET /v1/vault/items), or an async OCR job pipeline (TapScanner's POST /v1/jobs/prepare with result polling).
Vault covers the privacy side — cloud backup and restore of hidden media behind a session API — and All Languages Translator adds live-call interpretation: partner matchmaking, session history and per-call review records. Subscription state is server-side everywhere: Play purchase tokens are posted to billing endpoints and entitlements checked per device.
Frequently asked questions
What cloud APIs do scanner apps use?
All three scanners authenticate a user, then provision cloud storage: Simple Scan mints short-lived sync credentials at PUT /v1/sync/credentials, Genius Scan bootstraps a session and lists vault items, and TapScanner runs OCR as an async job pipeline (prepare, begin, result, artifacts). Share links and subscription receipts are registered server-side.
Which utility apps sync user files to the cloud?
Simple Scan, Genius Scan and Vault all do: the scanners sync PDFs to per-user vaults with daily/monthly byte quotas, and Vault backs up hidden media with a restore flow bound to the account. All Languages Translator syncs call sessions and history instead of files.
How is premium unlocked in these apps?
Through Play Billing tokens verified server-side: Simple Scan posts purchaseToken and orderId to /v1/billing/subscriptions and checks /v1/billing/entitlements/lookup, Genius Scan ties plans to its account session, and TapScanner redeems license keys at /v1/licenses/redeem.
