Banknova

Privacy Policy

Last updated: September 25, 2026

This policy explains what the Banknova app ("Banknova", "we", "us") collects, how it is collected, what it is used for, and who processes it. Banknova is built to collect as little as possible: there is no sign-up, no advertising and no tracking.

In short

  • The banknote photo you scan is sent for AI identification only after you allow it, and it is not stored.
  • The app never asks for your name, email address, location or contacts.
  • No ads and no tracking. Your advertising identifier is never read.
  • You can delete your data at any time in Settings → Delete my data.

1. What we collect and how

Banknote photos

When you scan, the photo you take or pick is sent to identify the banknote. Before it leaves your device, the app makes it smaller (at most 2000 pixels on the longest side) and removes its metadata (EXIF data, which can include location and device details). The photo exists only while your request is being answered: it is not saved on our server, and our server keeps no record of the request (execution logging is turned off). The AI provider receives only the photo and your language and region code, never your account ID.

Anonymous account ID

On first launch the app creates an anonymous account with a cloud hosting and authentication provider. It is a random identifier that is not tied to your name, email address or Apple Account. Our server uses it to confirm that a request comes from a real installation of the app with an active subscription. It also connects your subscription status and usage analytics.

Subscription status and purchase history

Purchases are made through Apple. A subscription management service receives your subscription status and purchase history from Apple together with the anonymous account ID, so the app and our server can tell whether your subscription is active. We never see your payment details.

Product interaction analytics

We use an analytics service provider (United States data region) to understand how the app is used, for example which screens are opened, whether a scan succeeded, and whether a purchase was started or completed. These events are linked to the anonymous account ID and include basic device information such as device model, operating system version, app version and language. They never contain photos, your name or your email address. The analytics service is set not to use your IP address to estimate your location. The advertising identifier (IDFA) is never read.

Your answer to "Where did you hear about us?"

During onboarding the app asks where you heard about Banknova, with a few options such as the App Store or social media. Your answer is sent to our analytics service provider as an analytics event.

Device language and region code

Each scan includes your device's language and region code (for example "en" and "US") so that the result is written in your language. This is a device setting, not your location. The app does not use GPS or location services.

Support messages

If you use the form on our support page, the name, email address, topic and message you enter are forwarded to us by a support form delivery service so that we can reply.

What we do not collect

The app never asks for your name, email address, phone number, location, contacts or any photos other than the ones you choose to scan. The camera is used only while you are scanning. The app has no ads and does not track you across other companies' apps or websites, so it never shows Apple's tracking permission prompt.

2. How we use the data

  • To identify the banknote in your photo and estimate its collector value.
  • To check your subscription and give you access to scanning.
  • To protect the service from abuse, for example with a daily scan limit per anonymous account and with an app integrity check that confirms requests come from the genuine app.
  • To understand and improve the app through usage analytics.
  • To answer your support requests.

We do not sell your data, use it for advertising or share it with data brokers. We do not use your photos to train AI models.

3. AI photo analysis and your consent

Before your first scan, the app clearly tells you that the photo will be sent to a third-party AI service provider to identify the banknote, and asks for your permission in the app. If the main AI model does not answer, a backup model from another AI provider may be used for the same purpose. If you decline, no photo is sent; scanning needs this permission.

You can withdraw your permission at any time in the app under Settings → Photo analysis permission. After you withdraw it, no more photos are sent.

Results are AI estimates, not formal appraisals. The collector value is always an estimated range, because condition changes the price. Banknova does not check whether a banknote is genuine or counterfeit.

4. Who processes your data

We use the categories of service providers below. Each one receives only the data it needs for the purpose described, processes that data only to provide its service to us, and gives it the same or equal protection as described in this policy.

  • Third-party AI service provider

    Purpose
    Identifies the banknote in your photo and estimates its value. A backup model from another AI provider is used only if the main model does not answer.
    Data
    Banknote photo, language and region code. Never your account ID, name or email address.

  • Cloud hosting and authentication provider

    Purpose
    Anonymous sign-in, an app integrity check that confirms requests come from the genuine app (using Apple's device verification), and hosting of this website.
    Data
    Anonymous account ID, app and device tokens used for the integrity check, and the IP address of website visitors.

  • Subscription management service

    Purpose
    Tells the app and our server whether a subscription is active.
    Data
    Anonymous account ID, subscription status and purchase history, app version and App Store country.

  • Analytics service provider

    Purpose
    Product analytics (United States data region).
    Data
    Anonymous account ID, in-app events, your onboarding answer, device model, operating system and app version, language.

  • Apple (App Store)

    Purpose
    Payments, subscriptions and App Store distribution.
    Data
    Purchases are handled under your Apple Account. We receive no payment details.

  • Server hosting provider

    Purpose
    Hosts our own server, which checks each scan request and passes the photo on to the AI provider.
    Data
    Scan requests while they are processed. Photos are held in memory only and are not stored.

  • Support form delivery service

    Purpose
    Forwards messages from our support form to our email inbox.
    Data
    The name, email address, topic and message you enter, and your IP address as part of the web request.

5. How long we keep data

  • Photos: not stored. They are discarded as soon as the answer is sent.
  • Anonymous account: kept until you delete it with Delete my data. If you only remove the app, the account stays unused and is no longer connected to your device.
  • Abuse protection: a daily count of scans per account, stored as a one-way hash of the account ID and replaced every day.
  • Subscription records: kept by Apple and our subscription management service for as long as needed to provide the subscription and as required by tax and accounting law.
  • Analytics: kept by our analytics service provider while needed to understand how the app is used. Delete my data resets the analytics ID on your device, so future events are not linked to past ones. To have past events deleted as well, contact us through the support form.
  • Support messages: kept in our inbox for as long as needed to handle your request.

6. Deleting your data and your rights

In the app, open Settings → Delete my data. This deletes your anonymous account, clears everything the app stored on your device, and resets the identifiers used by the subscription management and analytics services. The app then starts fresh, as on first launch.

Deleting your data does not cancel a subscription. To cancel, open the Settings app on your iPhone or iPad, tap your name, then Subscriptions.

Depending on where you live, you may have the right to access, correct, delete or export your data, and to object to or restrict its processing. To make a request, use our support form. You can also complain to your local data protection authority.

7. Where data is processed

Most of our service providers are based in the United States, and your data is processed on servers in the United States and possibly other countries where they operate. These countries may have different data protection laws from yours. We rely on the providers' contractual safeguards for these transfers.

8. Security

All data is sent over encrypted connections (HTTPS). Every request to our server must carry a valid sign-in token, and an app integrity check is used to confirm that requests come from the genuine app. The keys for the AI and subscription services are kept on our server and never ship inside the app.

9. Children

Banknova is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child has given us data, contact us and we will delete it.

10. This website

This website sets no cookies and uses no analytics. It remembers your language choice in your browser's local storage. Pages and fonts are served by a cloud hosting provider, which receives your IP address as part of ordinary web requests.

11. Changes to this policy

If we change this policy, we will post the new version on this page and update the date at the top.
