Open on Google Play

Simple Scan - PDF Scanner App is a Google Play utility from Easy inc. that turns the phone camera into a document scanner, saving captured pages as PDFs and running Google-powered OCR text recognition on them. Signed-in users can sync their scans to a cloud vault and pull them down on another device, within daily and monthly upload/download allowances, and can send a scanned PDF as a cloud share link straight from the Android share sheet. Free accounts get a smaller cloud-share storage cap than subscribers, while premium cloud plans (10 GB and 100 GB tiers, including a yearly 100 GB option) are sold as Google Play subscriptions that lift the storage and sync limits; an in-app account deletion removes the cloud account and its synced files. The app is distributed in the United States, India, Brazil and Indonesia to people digitizing paper documents on their phones, and competes with Adobe Scan, CamScanner, Genius Scan, TapScanner and India's Kaagaz.

Scanned PDFs synced to the cloud vault leave a trail of per-account records. Device capability flags and byte quotas — fileSyncEnable, ggOcrUsable, cloudFileShareUsable, dayUploadSyncFlow, monthDownSyncFlow — state whether a given device may sync, run Google OCR or share files, and how many bytes it may move per day and per month. Sync grants pin each user's documents to a storage location and a time-boxed identity (bucketName, bucketRegionName, identityId, identityPoolId, tokenExpireTimeMillis), while share registrations record each shared PDF by bucketKey and fileSize against a userId, alongside the freeStorageSpace and subscribeStorageSpace caps.

On the billing side, purchase records tie a Google Play purchaseToken and orderId to the account, and entitlement lookups return a SubscriptionPurchase whose expiryTimeMillis, paymentState and acknowledgementState decide whether the 10 GB or 100 GB cloud plan is live. Account deletions are keyed by userId, deviceId and deviceToken.

Document-management connectors use the sync grants to list and pull a user's scanned PDFs from the vault without opening the app; back-office OCR and ID-document extraction bots pick up newly registered shares by bucket key and file size; billing teams confirm a subscription's expiry and payment state before granting 100 GB of sync storage; and support tools run GDPR-style wipes that drop the cloud identity and zero the stored scan volume. openData Studio turns these vault, quota and entitlement records into callable open data.

Where teams use this data

  • Cloud vault credential broker

    A document-management connector calls PUT /v1/sync/credentials with the user's Firebase ID token, then uses the returned identityId, identityPoolId, bucketName and short-lived cloud token to list and pull scanned PDFs from the user's storage vault without opening the app.

  • Share-link intake for back-office OCR

    Intake bots watch POST /v1/shares/register for new bucketKey + fileSize registrations, then fetch the PDF from cloud storage and run downstream OCR or ID-document extraction using the same userId.

  • Premium entitlement audit

    Billing ops verify a device's cloud quota by pairing POST /v1/billing/subscriptions (purchaseToken, orderId, userId) with GET /v1/billing/entitlements/lookup, reading expiryTimeMillis and paymentState before granting 100 GB sync.

  • Account teardown / GDPR wipe

    Support tools call PUT /v1/account/delete with userId, deviceId and deviceToken to drop the cloud identity, then purge the synced vault so the user's stored scan volume is zeroed.

Frequently asked questions

How does Simple Scan authenticate its cloud calls?

Every cloud call sends custom app identity headers: app-version, appType=7, app-type=7, requestTime, systemVersion, phoneModel, uu-id (Firebase UID) and device-id. Sync additionally posts the Firebase ID token as token; the entitlement lookup uses the Play purchase token instead.

Where do scanned PDFs actually live?

PUT /v1/sync/credentials returns bucketName, bucketRegionName, identityPoolId and a short-lived cloud token. The app then uploads pages to cloud object storage; share-sheet files are also copied under a pdfs/ storage path before POST /v1/shares/register records the bucketKey.

Which fields control OCR and cloud-share?

PUT /v1/config/features returns ggOcrUsable, cloudFileShareUsable, deviceUsable and fileSyncEnable, plus dayDownSyncFlow / dayUploadSyncFlow / monthDownSyncFlow / monthUploadSyncFlow. The share-link response repeats those flags and adds freeStorageSpace vs subscribeStorageSpace.

How is a Play subscription turned into cloud quota?

After billing, POST /v1/billing/subscriptions sends purchaseToken, orderId, userId, accountId and deviceId. GET /v1/billing/entitlements/lookup?token=...&account_id=... then returns the expiryTimeMillis and paymentState used to unlock the 10 GB / 100 GB plans.
