Privacy Policy

Last updated October 5, 2026 · Applies to the Parchi Books app for iPhone, iPad and Android

The short version

1. Who we are

Parchi Books is made by Saada Labs LLC, a Texas limited liability company (“we”, “us”). This policy explains what happens to your information when you use the Parchi Books mobile app. Our company website is saada.tech.

2. Data on your device

Everything you keep in Parchi Books stays in a database on your phone or tablet:

The whole database is encrypted with AES-256 (SQLCipher). The key is kept in your device’s secure storage (the iOS Keychain or Android Keystore). We have no copy of this data and no way to access it. If you delete the app, it is gone unless you made a backup (section 6).

3. Scanning a receipt

When you scan, import or share a receipt into the app, Parchi Books sends the image or PDF over an encrypted connection (HTTPS) to our scan service. The service passes it to Google’s Gemini API, which reads the store, items, prices and totals and sends them back to your device for you to review.

4. Scan limits and abuse prevention

Each plan includes a monthly number of scans. To enforce that and to stop our scan service from being misused, each scan request also carries:

We store scan counts against these identifiers. Rate-limit records expire within a day, monthly scan counts within 70 days, and your cached plan status shortly after your subscription ends. We do not use them to identify you, build a profile or follow you across other apps or websites.

5. Subscriptions and purchases

Payments are handled entirely by Apple (App Store) or Google (Google Play). We never see your name, payment card or billing address. We use RevenueCat to manage subscriptions. When you buy or restore a purchase, RevenueCat receives the store’s purchase record, an anonymous app user ID it creates, and basic technical details such as app version, device model and country. It uses these to tell the app which features you’ve unlocked.

6. Cloud backup (optional)

Backup is off until you turn it on. When it’s on, a copy of your database goes to storage that belongs to you, not to us:

The backup is encrypted on your device before upload. The key is locked with a backup passphrase you choose and a recovery key you keep. Neither is ever stored by us or sent anywhere, so nobody can read your backup without one of them, including us, Apple and Google. If you lose both, the backup cannot be recovered.

Receipt photos are included only if you turn on “Back Up Receipt Photos”, and they are encrypted the same way. Each backup also stores a small amount of unencrypted information: your device’s name, the number of items and photos, the app’s data version and when the backup was made. The app uses these to warn you before one device overwrites another’s backup.

Data in iCloud or Google Drive is also covered by Apple’s or Google’s own privacy policies.

7. Google user data (Android backup)

On Android, backup asks you to connect Google Drive. Parchi Books requests only the drive.appdata permission, which lets it read and write its own hidden backup folder. It cannot see any other file in your Drive. Google also shares your Google account’s email address with the app, which is shown on the Backup screen so you know which account is connected. It stays on your device and is not used for anything else.

Parchi Books’ use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. We don’t use Google user data for advertising, we don’t sell it, we don’t transfer it to anyone else, and no person at Saada Labs reads it.

You can disconnect at any time in the app (Settings → Backup, tap the connected account, then Disconnect) or at myaccount.google.com/permissions.

8. Device permissions

PermissionUsed for
CameraPhotographing receipts. Only when you open the scanner.
PhotosChoosing a receipt image you already have. Only the image you pick is read.
Face ID, Touch ID or fingerprintApp Lock, if you turn it on. Your device checks the biometric itself; the app only learns whether it succeeded.
NotificationsReturn-window and quarterly tax reminders you switch on. They are scheduled on your device; we run no notification server.

Parchi Books does not access your location, contacts, microphone or other apps’ data.

9. App updates

The app can download small updates directly, without a full app store update, using Expo’s update service. When it checks, your device makes a standard request to Expo’s servers that includes your IP address, the app version and the platform. No receipt data is involved.

10. What we don’t do

11. Service providers

We use these companies to run the app. Each processes data only to provide its service to us.

ProviderWhat it doesData involved
Google (Gemini API)Reads receipt imagesThe receipt you scan
VercelHosts our scan serviceScan requests in transit, IP address, technical logs
UpstashStores scan counts and rate limitsInstall ID, purchase ID, IP address
RevenueCatManages subscriptionsAnonymous purchase ID, purchase records, device and app details
ExpoDelivers app updatesIP address, app version, platform
Apple / GoogleApp stores, payments, and backup storage you chooseCovered by their own policies

We may also disclose information if the law requires it, or to a successor if Saada Labs is reorganised or sold. Any successor would remain bound by this policy for data collected under it.

12. How long data is kept

DataKept
Receipts on your deviceUntil you delete them. Items carry a suggested 7-year retention period. You can clear expired items at any time; deleted items stay in Trash for 30 days.
Receipt sent for scanningNot stored by us. Google may retain it briefly for abuse monitoring (section 3).
Scan counts and rate limitsUp to 70 days
BackupsIn your iCloud or Google Drive until you delete them
Purchase recordsHeld by Apple, Google and RevenueCat as needed to provide and account for your subscription

13. Your choices and rights

Depending on where you live, you may have the right to access, correct, delete or get a copy of your personal information, and to object to certain processing. Because your data lives on your device, you can do most of this yourself in the app. For anything else, email us (section 17). We will respond within the time the law requires, and we won’t treat you differently for using these rights.

14. Security

Your data is encrypted on your device and in backups, and is sent over HTTPS. App Lock can keep the app closed behind your device’s biometrics or passcode. No system is perfectly secure, but the safest data is data we never hold, and we hold very little.

15. Children

Parchi Books is meant for adults managing their own expenses. It is not directed to children under 13, and we do not knowingly collect personal information from them.

16. Changes to this policy

If we change this policy, we’ll post the new version here and update the date at the top. If a change materially affects how your data is handled, we’ll also tell you in the app before it takes effect.
