Privacy policy

Last updated 27 October 2026

The short version

• There is no account. We never ask for your name, email address, location or contacts.
• There are no ads and no tracking, in the app or on this website.
• The app sends anonymous usage counts, tied to a random-looking device key rather than to you, so we can see how Moodwindow is used.
• We do not sell or share personal data.
• Your favourites, sound mixes and settings stay on your device.

Who we are

Moodwindow is made by PolarCurve LLC (“we”, “us”). This policy covers the Moodwindow apps for Android TV, Google TV, Fire TV and Android phones and tablets, the Apple and smart-TV versions as they are released, and this website, moodwindow.com. You can reach us at support@moodwindow.com.

What the app sends over the internet

The app streams its scene videos and the scene list from cdn.moodwindow.com. Like any request on the internet, each download sends your device’s IP address, the name of the file and standard technical details such as the app’s user agent. Our content network is run by Cloudflare, Inc., which keeps standard request logs to deliver and protect the service. We do not use these logs to identify you, build a profile or follow you across apps. Cloudflare’s handling is described in its privacy policy.

Usage counts. When the app starts, and when you leave a scene, it sends our server at moodwindow.com (also run on Cloudflare):

• a device key: 12 characters made by one-way hashing the ID your device gives this app. It identifies the installation, not you, and is shown in the app under Settings → About, so you can quote it to support;
• the platform (for example Android TV or Fire TV) and the app version;
• whether Premium is active, and which plan;
• simple counts: which scenes you started, minutes watched and when the Premium screen was shown.

Your IP address is used for a moment to limit abuse and is never stored, and we record no location, not even your country. We use these counts to know how many devices use Moodwindow, which scenes people watch and whether the app is worth improving. They contain no name, email address, precise location or advertising ID, and they are never sold or shared.

The app contains no third-party advertising, analytics, crash-reporting or tracking software.

What stays on your device

Your saved scenes, sound mixes, sleep-timer choices, settings, whether Premium is unlocked, and cached videos are stored only on your device. We have no copy. Uninstalling the app, or clearing its data, deletes them.

The sound is generated on your device. The app does not use the microphone or the camera.

Purchases

Premium is bought through Google Play, the Amazon Appstore or Apple’s App Store. The store handles the payment and tells the app only what it needs to unlock Premium, such as which product you bought. We never see your name, card or bank details. The store’s own privacy policy applies to the payment.

When a purchase or free trial starts, the app tells our server which plan it was, with your device key and a one-way hash of the store’s purchase reference, so we know a sale happened and count it only once.

If support activates Premium for you by hand, or moves it to a new device, we store the device key, the plan, its end date, and the email address you gave us.

For Samsung and LG TVs, we plan to offer Premium on this website, with payments processed by Stripe. We will update this policy before that launches.

This website

This website sets no cookies of its own and uses no analytics, ads, tracking pixels, third-party fonts or third-party scripts. It is served by Cloudflare, which keeps standard request logs and may set a strictly necessary security cookie to protect the site from abuse. The sound in the website’s demo is generated in your browser; nothing about it is sent anywhere. The demo’s videos load from cdn.moodwindow.com, as described above.

How long we keep it

A device that has not opened Moodwindow for about 13 months is deleted automatically, unless it holds a licence from support. Daily totals (for example “120 devices active on Monday”) contain no device key and are kept. Purchase and licence records are kept for as long as accounting and support require.

When you write to us

If you email us, we receive your email address and whatever you include in your message. We use them only to answer you, and keep them for as long as the conversation and our ordinary business records require.

AI

Scenes are created with the help of AI. No personal data is used to make them, and the app does not send your data to any AI service.

Children

Moodwindow is made for a general audience and is not directed at children under 13. It does not knowingly collect personal information from children, and its usage counts are not linked to a person.

Your rights

Depending on where you live (for example in the EU, the UK or California), you may have the right to access, correct or delete personal data about you, to object to its use, and to complain to a data protection authority. We cannot link usage counts to your name, so to see or delete the data for your device, send us its device key (Settings → About) at support@moodwindow.com; the steps are under Delete your data. Where data protection law requires a legal basis, request logs, usage counts and abuse limits rest on our legitimate interest in delivering, securing and improving the service; licences on providing what you asked support for; and emails on answering your request. Cloudflare operates worldwide, so request data may be processed outside your country.

Changes

If this policy changes, we will update this page and the date above. If a change affects what we collect, we will say so here before it takes effect.
