Privacy Policy

Effective date: November 11, 2026

WarrantyVault is made by Lennox Digital ("we"). This policy explains what the app does with your information. The short version: your items, photos and receipts stay on your phone. We only hold an email address, a user ID and your purchases, and only if you choose to sign in or buy Pro.

What stays on your phone

Everything you put into WarrantyVault is stored only on your device:

• items and their details (names, brands, models, serial numbers, stores, prices, purchase dates, rooms, categories, tags and notes);
• photos, receipt images and the text read from them;
• manuals you attach, warranty and claim details, case numbers and claim notes;
• the name, contact details, address and insurer you enter for reports;
• your settings, PIN (stored as a one-way hash) and reminder schedule.

We can't see any of it. It is not sent to us or to anyone else.

Receipt reading happens on your phone. The text-reading engine and its English language data are built into the app, so receipt images are never uploaded and no outside service is involved.

Reminders are scheduled by your phone's notification system. No server is involved.

Files you create (claim packet PDFs, the home inventory report, the encrypted backup, the spreadsheet and the calendar file) are made on your phone. They only go where you send them, for example your email, cloud drive or calendar. The backup file is encrypted with AES-256 using a password you choose. We don't have the password and can't recover it.

Android's automatic backup is turned off for WarrantyVault, so your data is not copied to Google Drive by the system. Use the encrypted backup file to move to a new phone.

The optional Lennox Digital account

You don't need an account to use WarrantyVault. If you choose to sign in, for example to use one Lennox Digital Pro subscription in all our apps, we store the following. You can sign in with Google, with Apple (on iPhone) or with your email address and a 6-digit code. If you use Google or Apple, they confirm who you are and share your email address with us under their own privacy policies; we don't get your password or anything else from your Google or Apple account.

• your email address (with Sign in with Apple you can hide it, and we get a relay address instead);
• a user ID that links your account to your purchases;
• the sign-in method you used.

Your items, photos and receipts are not part of the account and are never uploaded.

The account runs on our own server, hosted by Supabase (our service provider) in the United States. Data is sent over encrypted connections (HTTPS).

Purchases

WarrantyVault Pro and Lennox Digital Pro are sold through Google Play (and the App Store on iPhone). Google or Apple handle your payment; we never see your card details. To unlock Pro and let you restore it, the app sends the store's receipt to our server, which checks it with Google or Apple and keeps a record of what you bought: the product, when it was bought, when it renews or ends, and the store's purchase token or transaction ID. If you're signed in, the record is linked to your user ID, which is how one Lennox Digital Pro purchase unlocks our other apps. Google and Apple also tell our server when a subscription renews, ends or is refunded. Purchase records are kept on the same server (Supabase, United States).

What we don't do

• No ads, and no advertising or tracking SDKs.
• No analytics, crash reporting or usage tracking.
• No location, contacts or device identifiers collected.
• We don't sell or share your data. Service providers (Supabase for our server, Google and Apple for sign-in and purchases) process it only to provide sign-in and purchases.

Deleting your data

• Items on your phone: delete any item from its page, or use Settings > Delete all data to erase everything. Uninstalling the app also removes it.
• Your account: Settings > Delete account deletes your Lennox Digital account and its purchase records in every Lennox Digital app. If you have a subscription, cancel it in Google Play or the App Store too, or it keeps renewing.
• You can also email support@lennoxdigitallabs.com to ask us to delete your account. We do this within 30 days.

We keep account data only while your account exists. Stores may keep their own purchase records under their own policies, and we may keep transaction records for as long as tax law requires.

Children

WarrantyVault is meant for adults (18 and over) and isn't designed for children. We don't knowingly collect data from children.

Changes

If we change this policy, we'll update this page and the effective date. If a change affects what we collect, we'll say so in the app's release notes.
