Privacy Policy

This Privacy Policy explains what information the Christmas List: My Budget app (also listed as This Christmas Gift List, “the app”) and this website collect, how it is used, and the choices you have. It applies to the app on iPhone, iPad and Android, and to christmasbudget.app.

Who we are

The app is made by Stratus Cube, a business name (DBA) of Anthony Tietjen, who is responsible for the information described in this policy and is the data controller for the purposes of the GDPR. You can reach us through the contact details at the end of this policy.

Your lists stay on your device

The events, people, gifts and budgets you enter are stored on your device. We do not receive them and cannot see them.

• On iPhone and iPad, the app can back your list up to your own iCloud account.
• On Android, the app can back your list up through Google’s Android backup service to your own Google account.
• If you export a backup file, it goes wherever you choose to send or save it.

These backups are handled by Apple or Google under their own privacy policies. We have no access to them.

Information we collect

When you use the app, we may collect:

• Device information, such as operating system version, device model, language and region, display settings, and installed memory
• App activity, such as app launches and the app version
• Purchase activity, such as which Christmas List Plus plan you looked at or chose and whether the purchase went through
• A randomly generated installation identifier, described under “Analytics” below
• On Android, advertising identifiers and ad interaction data collected by Google, as described under “Advertising” below

On this website, we collect only anonymous page-view statistics. If you joined our Android waitlist before the Android app launched, we also have the email address you gave us.

Analytics

The app reports basic usage analytics to us so we can understand how many people use it and on what kinds of devices. When the app launches, it may send us the device information listed above together with a randomly generated installation identifier.

That identifier is created on the device the first time the app runs and is not derived from your device’s hardware, your Apple or Google account, or your advertising identifier. It is not linked to your name or email address, and deleting and reinstalling the app replaces it with a new one. We use it only to tell one installation from another, so repeat launches aren’t counted as new users.

This analytics data is stored with Google, on servers in the United States.

Purchases

Christmas List Plus is sold through the Apple App Store and Google Play, which process your payment. We receive only what is needed to confirm what you bought, never your payment details.

Advertising

On iPhone and iPad, the app shows no third-party ads. Its only promotions are for our own apps, it contains no advertising SDK, and it does not track you.

On Android, people who haven’t bought Christmas List Plus see ads served by Google AdMob. They are never personalized: the app asks Google for non-personalized ads and turns on Google’s restricted data processing for every request. To show and measure ads and prevent fraud, Google stores and reads information on your device and collects your device’s IP address (which gives an approximate location), the Android advertising ID and app set ID, how you interact with ads, and diagnostic information. This happens even though ads aren’t personalized, because the information is used for purposes such as limiting how often you see the same ad and detecting invalid or fraudulent activity. You can reset or delete your advertising ID in Android’s settings.

We do not build advertising profiles about you, and we do not sell your personal information or share it for cross-context behavioral advertising. Ads in the app are limited to content we consider appropriate for its audience.

Google processes the data it collects through AdMob as described in How Google uses information from sites or apps that use our services. You can also review Google’s Privacy Policy and the list of ad technology providers that may be involved in serving ads.

Consent in the EEA, the UK, and Switzerland

If you are in the European Economic Area, the United Kingdom, or Switzerland, the Android app asks for your consent, using Google’s consent form, before information is stored or read on your device for advertising. If you decline, the app keeps working normally, and Google may still show limited ads, which use less information. You can change your choice at any time with Privacy Options in the app’s menu.

This website

christmasbudget.app uses Vercel Web Analytics to count page views. It does not use cookies and does not identify individual visitors. Before the Android app launched, the site offered an Android waitlist. If you joined it, your email address is stored with Google and used only to tell you the Android app is available. The waitlist is now closed. To have your address removed, contact us.

How we use information

• To provide, maintain and improve the app
• To understand how the app is used and which devices to support
• To confirm purchases
• To show ads on Android to people who haven’t bought Christmas List Plus
• To reply when you contact us, and to email you if you joined the waitlist
• To comply with legal obligations

How we share information

We share information only with service providers that help us run the app and website: Apple and Google (app stores, backups, analytics storage and, on Android, advertising) and Vercel (website hosting and page-view statistics). We may also share information with law enforcement or other parties if we are required to by law.

Data retention

We keep the information we collect for as long as it is needed for the purposes described in this policy, or until you ask us to delete it.

International transfers

Analytics data is stored with Google in the United States, and Google and Vercel may process data outside your country as well. If you are in the EEA, the UK, or Switzerland, this means your information is transferred to the United States. These transfers rely on the safeguards our providers offer, such as the EU–U.S. Data Privacy Framework and its UK and Swiss extensions, or Standard Contractual Clauses.

Legal bases (EEA, UK, and Switzerland)

• Consent, for storing and reading information on your device to show ads. You can withdraw it at any time from Privacy Options in the app.
• Legitimate interests, for basic usage analytics, keeping the app and website secure, detecting invalid or fraudulent ad activity, and replying when you contact us.
• Consent, for emailing you if you joined the Android waitlist.

Your rights

Depending on where you live, you may have the right to access, correct or delete your information, to restrict or object to how we process it, to data portability, to withdraw consent at any time, and to opt out of the sale or sharing of personal information. We do not sell personal information or share it for cross-context behavioral advertising. If you are in the EEA, the UK, or Switzerland, you can also lodge a complaint with your local data protection authority. To exercise any of these rights, contact us.

You can also reset your advertising identifier in your device’s settings, and replace the installation identifier we use for analytics by deleting and reinstalling the app.

Security

We take reasonable measures to protect the information we collect from unauthorized access, disclosure, or destruction. However, no system is perfect, and we cannot guarantee the security of your information.

Children’s privacy

The app is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13, and if we become aware that we have, we will delete it as soon as possible.

Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will change the date below, and we will tell you in the app if the changes are significant.
