Privacy Policy
Last updated: October 9, 2026
This policy covers the MareArts website (marearts.com), our desktop apps, the ANPR SDK and ANPR SDK Server, and the ANPR Mobile App. It says what each one sends to us, what stays on your device, and how to ask us to delete your data.
1. Summary
| Product | What reaches MareArts |
|---|---|
| Website | Account email, purchases and licence records, page analytics |
| Desktop apps | Sign-in (email and licence signature), update checks, anonymous usage events in some apps |
| ANPR SDK and ANPR SDK Server (MASS) | Model downloads and sign-in. Images only when you call a cloud feature |
| ANPR Mobile App | Sign-in, analytics and crash reports. Detections, photos and location only when you turn on Sync |
We do not sell personal data, we do not show ads, and we do not store payment card details.
2. Website
Your account
You sign in with your email address and a one-time code (Shopify Customer Accounts). After you buy, the account pages show your licences, subscriptions and, for ANPR, the detections, rules, statistics, images and team members you sync from your apps.
Purchases
Payments are processed by PayPal. We never see or store your card details. We keep a record of each purchase (an order and a licence record) so we can issue and renew your licence.
Analytics, cookies and browser storage
| What | Why |
|---|---|
| Google Analytics | Page views and visit statistics |
| ClustrMaps visitor map (footer) | Counting visits by country; it receives your IP address |
| Shopify cookies and scripts | Running the store, the cart and sign-in |
| Browser storage on your device | Light/dark theme, account page preferences and a cached profile picture |
| Article view counter | Counts views of Open Lab posts. No account details are attached |
| IP-based country lookup (ipapi.co) | Showing prices in your currency |
Pages with videos embed YouTube, which sets its own cookies when you play a video. Checkout loads PayPal's script.
Contact form
Messages you send through the contact form reach us by email and are used only to answer you.
3. Licence accounts
For every licence we store your email address, the product and plan, start and end dates, the licence key and signature, and the subscription ID. For team purchases we also store who paid. A team purchaser sees only a masked key; the full key goes to the licence owner only.
We email you about your licence (issue, renewal, expiry, cancellation) through Amazon SES. Our staff receive an internal notification of each purchase with the email, product and plan, so we can support you.
4. Desktop apps
All desktop apps sign in by sending your email and licence signature to our licence server, and check our download server for updates. Your files, projects and settings stay on your computer.
| App | What else is sent |
|---|---|
| ANPR Desktop (MAD) | Anonymous usage events. With cloud sync on: detections and rules to your account. With cloud ANPR or vehicle recognition on: the image you send. Map addresses use OpenStreetMap with rounded coordinates |
| Markdown Studio (MARK) | Anonymous usage events. Your documents stay local |
| Backup System (BACK) | Anonymous usage events. Backups go only to the destinations you choose |
| Video Editor (VIDE) | Anonymous usage events. Your projects stay local |
| Image Viewer (MIV) | Anonymous usage events. Your pictures stay local |
| Remote Desktop (REMO) | Anonymous usage events. Screen sharing goes directly between your computers over an encrypted connection, not through our servers |
| MAST Stitching Studio (MAST) | A device ID of your graphics card at sign-in, used to tie the licence to the machine. No usage analytics. Video goes only to the stream outputs you set up |
Anonymous usage events are sent to Google Analytics and contain the app name, version, operating system, the screen or action used, and a random install ID. They never contain your email, file names or content.
5. ANPR SDK and ANPR SDK Server (MASS)
- Licence checks run offline on your machine.
- Models are downloaded from our servers after sign-in.
- Recognition runs locally. An image is sent to us only when you call a cloud feature (for example vehicle make/model/colour recognition) or the public test API.
- MASS sends webhooks only to the addresses you configure, and checks our server for updates.
- Neither collects usage analytics.
6. ANPR Mobile App
On your phone
Plates are read on the phone. Scan history, photos and locations are stored in the app's local database. Photos are kept for 30 days by default (7 days on the trial), and you can change this or delete everything in Settings. The local database is not encrypted, so protect your phone with a passcode.
Location
If you allow location, each scan is tagged with its GPS position on the phone. Location is sent to us only as part of a synced detection (see Sync).
Sync (optional)
Sync needs a signed-in licence and is off by default. When you sync, each detection is uploaded with the plate, time, confidence, GPS position and address, the photo, the matched rule, the app and OS version, the phone model and a device ID. Rules and watchlists also sync, and can be shared with your team leader and members. You can see this data on the website account pages. Synced data is kept for up to 13 months (395 days) and then deleted automatically.
Cloud recognition (optional)
If you choose cloud recognition, the photo is sent to our server, which passes it to Google's AI service to read the plate. We do not store the photo for this feature.
Webhooks (optional)
If you add a webhook, detections (with or without photos, as you choose) are sent to your own address. We do not receive a copy.
Services used by the app
| Service | What it receives |
|---|---|

| Firebase Crashlytics | Crash reports |

The app has no ads and no in-app purchases. Licences are bought on marearts.com.

8. How long we keep data
| Data | Kept |
|---|---|
| Account and licence records | While you have an account, and as long as tax and accounting law requires for purchases |
| Synced mobile detections, photos, rules | Up to 395 days, then deleted automatically |
| Data on your devices | Until you delete it |
9. Your rights and deleting your data
You can ask to see, correct, export or delete your personal data, and object to its use (GDPR, CCPA and similar laws). In the mobile app, "Delete All" marks your synced data as deleted on the next sync, and it disappears from your account pages. To erase it completely, or to delete your account and everything linked to it, email hello@marearts.com from your registered address with "Account Deletion Request" in the subject. We delete it within 30 days.
For security we reply only to the email address registered on the account.
10. Children
Our products are not meant for children under 13, and we do not knowingly collect their data.
11. Changes
When this policy changes we update the date at the top of this page. Significant changes are announced on the website or in the apps.
