Terms of Use

Last updated: 22 September 2026

These Terms govern your use of the Natsumar mobile app ("Natsumar", "the app"), provided by Omar Martín, Spain ("we", "us"). By installing or using the app you agree to these Terms. If you do not agree, do not use the app. How we handle personal data is explained in the Privacy Policy.

1. Who can use it

Anyone can browse and save wallpapers. To create an account you must be at least 14 years old (or the age of digital consent in your country, never under 13).

2. Your account

An account is optional; it only syncs your favourites across devices. You sign in with Apple or Google and are responsible for keeping that sign-in secure. You can delete your account at any time directly in the app (Account → Delete account), which erases it immediately, or by emailing support@natsumar.com — see how to delete your account.

3. Ownership and licence to use the wallpapers

All wallpapers, illustrations and other artwork in Natsumar (the "Artwork") are owned by us or licensed to us. All rights not expressly granted to you are reserved.

We grant you a personal, non-exclusive, non-transferable, non-sublicensable and revocable licence to download Artwork from the app and use it as the wallpaper or lock-screen image of your own devices, for personal, non-commercial use only. Sharing a wallpaper with a friend through the app's share button, for their own personal use, is allowed.

Without our prior written permission you may not:

• redistribute, sell, rent, sublicense or otherwise make the Artwork available to third parties (for example, re-uploading it to other wallpaper apps or sites);
• print or apply the Artwork to physical or digital products, merchandise or print-on-demand items (posters, clothing, stickers, phone cases and similar);
• modify or adapt the Artwork for any commercial purpose, or use it to promote or brand any product, service or business;
• remove or alter any copyright or attribution notice; or
• use the Artwork or any content of the app to train, fine-tune or develop artificial-intelligence or machine-learning models, or collect it by automated means such as scraping or bulk downloading.

Any use outside this licence ends it automatically, and we may request takedowns and exercise any other remedy available by law.

4. Price, purchases and advertising

Natsumar is free, shows no advertising and offers no in-app purchases. If we ever introduce optional purchases or advertising, they will be clearly shown in the app, purchases will be processed by the App Store or Google Play under their terms, and we will update these Terms and the Privacy Policy first.

5. Acceptable use

You agree not to reverse engineer or extract the app's source code except where the law allows it, use the app to break any law or third-party right, or interfere with the security or operation of the service.

6. Availability and warranties

We work to keep Natsumar available and working well, but it is provided "as is" and we cannot guarantee it will be uninterrupted or error-free. The catalogue may change over time. Nothing in these Terms limits the rights you have as a consumer under the law of your country of residence.

7. Liability

To the extent permitted by law, we are not liable for indirect or consequential damages arising from the use of a free app. This does not limit liability that cannot be excluded by law, such as for wilful misconduct or gross negligence.

8. Changes and termination

We may update these Terms; significant changes will be announced in the app before they apply. You can stop using Natsumar at any time by deleting your account (if you have one) and uninstalling it. We may suspend access if these Terms are seriously breached.

9. Law and disputes

These Terms are governed by Spanish law. If you are a consumer, you may bring a claim before the courts of your place of residence, and mandatory consumer protections of your country still apply. The EU online dispute resolution platform is available at consumer-redress.ec.europa.eu.
