Terms of Service

Last updated: September 7, 2026.

  • These Terms cover Floorp for Desktop, Floorp for iOS, floorp.app, and the Floorp Blog.
  • Your rights under open-source licenses are preserved. Optional external services have their own terms.
  • Floorp does not promise uninterrupted or error-free operation. Your statutory consumer rights are preserved, and Floorp Projects remains responsible where the law does not allow liability to be excluded.
  • Important changes will be announced in advance. Where your consent is required, continued use alone will not replace it.

This is a summary. The sections below explain the scope, responsibilities, and how changes take effect.

1. Scope and operator

Floorp Projects is operated by Ryosuke Asano as a sole proprietorship. The contracting party for these Terms is Ryosuke Asano, operating under the name Floorp Projects.

Floorp Projects develops Floorp and operates the official website at floorp.app and the Floorp Blog at blog.floorp.app. These Terms explain the conditions for using Floorp for Desktop, Floorp for iOS, and these sites. The software licenses and the terms of external providers described below apply to their respective subjects.

These Terms apply when you browse or use our website and blog. Where applicable law or the advertising service's requirements require consent for advertising, cookies, or related processing, we will request that consent before the processing begins.

Where we clearly state before a download that these Terms apply and give you an opportunity to review their contents, you are deemed to have agreed to these Terms when you download Floorp. This applies only to the extent permitted by applicable law; where express consent or another procedure is required, we will follow that procedure.

This agreement does not include or replace separately required consent, including consent for advertising or the processing of personal information. Changes to these Terms are governed by section 7. Posting these Terms or your continued use alone does not replace consent that must be obtained separately.

2. Open source and trademarks

Floorp includes software under the Mozilla Public License 2.0 and other open-source licenses. The license and copyright notices supplied with the software or its source code identify the terms for each component. You may use, copy, modify, and redistribute those components as their licenses permit. These Terms do not reduce those rights; the applicable open-source license takes precedence if there is a conflict on that subject.

Software licensing and permission to use names and logos are separate. An open-source license does not generally grant permission to use Floorp or another party's trademarks, except where the license expressly permits it. Uses permitted by law remain available. Rights in website and blog text, images, and other material remain with their respective owners; any separately stated licenses or use conditions apply to that material.

3. External services and the App Store

Mozilla Account and Sync are optional services provided by Mozilla. When you use them, Mozilla's account terms and privacy notice apply. Search providers, extensions, and other external services may have their own terms, eligibility requirements, and privacy notices. Check these when choosing to use a service. Floorp Projects does not operate Mozilla Account or Sync servers or set another provider's terms.

For Floorp for iOS obtained through the App Store, Apple's standard end-user license agreement (EULA) applies unless a custom EULA is provided for the app in your country or region. These Terms, as published on this page, do not by themselves replace the EULA applicable through the App Store. The rights granted by the applicable open-source licenses described above remain in place.

4. Use and service availability

Please respect applicable law and the rights of others when using Floorp. Do not gain unauthorized access to Floorp Projects' sites or online systems or intentionally disrupt their operation, including by imposing excessive load. These conditions do not restrict modifications or redistribution permitted by the software licenses.

Features and availability vary by operating system, version, region, and provider. We may change or end features or services for maintenance, security, or other operational reasons. For planned changes that substantially affect use, we will provide advance notice on the website, blog, or in the app. Urgent security measures may be taken before notice; in that case, we will explain the change as soon as reasonably possible.

5. Privacy and your choices

Our Privacy Policy explains how information is handled, including local browser data, optional synchronization, website and blog advertising, retention, deletion, and contact requests. Agreement to these Terms is not consent to optional advertising or other data processing that requires separate consent. Use the relevant app, account, or website controls to manage your choices.

You may stop using Floorp or an optional service at any time. Stopping use or uninstalling an app does not necessarily delete account data or synchronized copies. The Privacy Policy explains the relevant controls and deletion methods.

6. Warranties and responsibility

Floorp software and sites are provided in their current state and with the functionality available at the time. We do not promise uninterrupted operation, complete freedom from defects, compatibility with every device or website, or recovery of all lost data. This does not exclude warranties or obligations that applicable law requires us to provide. Please keep backups of important data.

Floorp Projects' responsibility for loss caused by use of, or inability to use, Floorp or its sites is determined by applicable law. These Terms do not exclude or limit our liability for intentional misconduct or gross negligence, or any other liability that cannot lawfully be excluded or limited, including liability for death or personal injury where such restrictions are prohibited. Your mandatory consumer rights remain unaffected.

7. Changes to these Terms and consent

September 7, 2026 update: We clarified the explanations of revisions and the examples of when consent is required. We also specified the point of agreement for downloads preceded by a notice that these Terms apply, and clarified that these Terms apply when browsing or using the website and blog, with prior consent requested where required for advertising or cookies. This download provision concerns downloads made after that notice; it does not treat earlier downloads as agreement. Responsibilities, separately required consent, and advance notice when conditions of use change remain as described in these Terms. This update does not introduce new uses of personal information.

We may revise these Terms when reasonably needed to reflect changes in features, services, or legal requirements. We will publish the full revised text and the last updated date on the website. Corrections and explanatory edits that do not change the conditions of use are announced through the updated text and date.

A revision to these Terms does not always require a new consent action. A change without your individual agreement takes effect only where applicable law permits it and its requirements are met. Under Japan's rules on standard form contract terms, where applicable, this may include revisions that serve users' general interests, or revisions that are consistent with the purpose of the contract and reasonable in light of the need for the change, its content, and other relevant circumstances.

When changing the conditions of use set out in these Terms, we will publish the full revised text, the reasons for the change, and its effective date on the website before the change takes effect. This advance notice applies whether or not individual agreement is required. We will also announce the main points of important changes in advance through the website, blog, or an appropriate in-app notice, observing any notice period required by applicable law. Required notice methods and other legal procedures must also be followed.

Examples of when we ask for agreement or consent: If we introduce features or changes such as the following in the future, we will obtain the enrollment or consent required for each case:

  • New paid features or subscriptions: we will explain the price, automatic renewal, and cancellation conditions before you choose to subscribe or purchase. Revising these Terms alone will not enroll you in a paid service or start charging you.
  • Changes to your obligations or rights: for example, adding a new obligation to compensate us or seeking broader permission to use content you submit. If a change cannot lawfully take effect without your individual agreement, we will obtain it before applying the change to you.
  • New uses or recipients of personal information: for example, using personal information for a new purpose beyond what is necessary to achieve the originally specified purpose, or making a new disclosure to a third party that requires consent under applicable law. Where the processing requires your consent under applicable law, we will explain the purpose, recipients, and other information needed for your decision and obtain consent before the processing begins.
  • Advertising cookies or personalized advertising: where consent is required by applicable law or the advertising provider's applicable requirements, we will ask for your choice through the relevant consent screen. As explained in section 5, agreement to these Terms or a revision does not replace consent required for advertising or other data processing.

When we ask for agreement or consent, we will make the relevant conditions and changes available before they apply and explain what you are being asked to accept. We will use an action that clearly expresses your choice, such as selecting a button to subscribe on the stated terms or to enable the described data transmission. Continued use alone will not replace consent that must be obtained separately.

Revising these Terms or obtaining your agreement does not reduce the open-source license rights described in section 2 or the mandatory consumer rights described in section 6. Open-source rights remain subject to the applicable license's own conditions.
