Privacy Policy

Effective: November 9, 2026
App: Scanzly (Android package com.lennoxdigital.scanzly), by Lennox Digital Labs LLC ("Lennox Digital", "we")
Contact: support@lennoxdigitallabs.com

Scanzly is built so your documents never leave your phone. This policy explains what stays on your device, the little we store when you choose to use an account or buy Pro, and how to delete it.

1. What stays on your device

Scanzly does its work on your device. We never receive, upload or store your files. This includes:

• PDFs, scans and photos you open, create or edit
• Signatures and initials you save
• The quick-fill details you enter for forms (name, email, phone, address)
• Flash card decks, practice tests and slide decks
• The search index Scanzly builds so you can search inside your files
• Your settings, including the app PIN, which is stored only as a one-way hash

Text recognition (OCR), redaction, compression, conversion, Reading view and flash card generation all run on the device. Read aloud uses your phone's built-in text-to-speech service.

Your files leave the device only when you choose to share or export them, and then they go only to the app or place you pick.

2. Downloads the app makes

The first time you use text recognition (OCR) for a language, Scanzly downloads that language's data file from the jsDelivr content delivery network (cdn.jsdelivr.net). The request contains no information about you or your files. Like any web server, the network sees your IP address in order to send the file. After that, OCR for that language works offline.

3. The optional Lennox Digital account

You never need an account to use Scanzly's free tools. If you choose to sign in, for example to use Lennox Digital Pro across our apps, we store:

• your email address
• an account ID, and which sign-in method you used
• your purchase history with us: which Lennox Digital subscriptions you bought, in which app and store, and when they renew or end

We use this only to sign you in and to unlock Pro in our apps. The account and purchase records are kept on our server at Supabase (our database and sign-in provider, hosted in the United States), which processes the data for us. Your files are never part of the account.

Sign-in providers. You can sign in with Google, with Apple (on iPhone), or with your email address and a one-time code we email you. If you use Google or Apple, that company confirms who you are and gives us your email address (with Apple, you can choose a private relay address) and an ID for your account. We don't receive your Google or Apple password, contacts or other data. Their own privacy policies apply to the sign-in itself.

4. Purchases

Subscriptions (Scanzly Pro and Lennox Digital Pro) are sold through Google Play (and, on iPhone, the App Store). Google and Apple handle payment, and we never see your card or bank details. To check a purchase and know whether Pro is active, the app sends the store's purchase receipt to our server, which confirms it with Google or Apple and records the product, its status, the renewal or expiry date and the store's transaction ID. Google and Apple also tell our server when a subscription renews, is cancelled or is refunded. These records are kept at Supabase (United States). If you are signed in, they are linked to your account so Pro works in every Lennox Digital app; if not, they aren't linked to any name or email.

5. What we don't do

• No ads, and no advertising or tracking SDKs
• No analytics or crash-reporting services
• We don't sell or rent your data, and we don't share it with anyone except the service providers named above, who process it only for us
• We don't read, scan or train AI on your documents

6. Deleting your data

• Account: in the app, go to Settings → Account → Delete account. This deletes your account and its purchase records (section 3) from every Lennox Digital app. Subscriptions are managed by Google Play or the App Store, so cancel them there to stop renewals.
• Files on your device: Settings → Data → Erase all data, or uninstall the app.
• By email: write to support@lennoxdigitallabs.com from your account's email address, and we will delete your account within 30 days.

7. Security

Connections to our account and purchase server use HTTPS, and the server only lets each account read its own records. PDFs you protect with a password are encrypted with AES-256 on the device.

8. Children

Scanzly is meant for adults (18 and over) and is not directed at children. We don't knowingly collect data from children. If you believe a child has created an account, email us and we will delete it.

9. Your rights

Depending on where you live, for example under the GDPR or US state privacy laws, you may have the right to access, correct, delete or export your personal data, or to object to how it is used. Email support@lennoxdigitallabs.com and we will respond within 30 days.

10. Changes

If we change this policy, we'll update the date at the top and, for significant changes, tell you in the app.
