Terms of Service

Last updated: October 28, 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.
  • Financial support is optional. One-time and monthly support require a separate application; monthly support renews until cancelled.

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.

8. Financial support

Optional support and recipient: You may choose to support Floorp's development and operation through the payment options made available on our support page. For direct support, the recipient and contracting party is Ryosuke Asano, operating as Floorp Projects, as identified in section 1. Support funds cover development, maintenance, build and distribution infrastructure, servers and related services, development subscriptions including AI services, and development hardware. This section concerns voluntary financial support, not a purchase of browser access, a paid membership, an investment, or an entitlement to a particular feature, release date, advertisement removal, or priority support. Choosing not to contribute, or cancelling support, does not remove your existing browser functionality or open-source rights. Any future offer of paid benefits requires separate terms and enrollment.

Your application: Before you confirm a payment, we show the frequency, currency, total amount submitted for payment, payment timing, and cancellation and refund conditions. Floorp Projects does not add tax or a separate handling fee to the displayed support amount. You must separately confirm the payment or recurring-payment application on those terms. Downloading or using Floorp, accepting the general Terms, or visiting a payment return page does not authorize a charge. Use only a payment method you are authorized to use, and obtain any consent required by applicable law.

One-time support: A one-time contribution is charged once when the payment is completed. It does not create a monthly subscription. Payment processing may require additional authentication, and the final status is determined by the payment provider's confirmed records rather than a redirect alone.

Monthly support and renewal: For monthly support, the first payment is due when you subscribe. We then charge the agreed monthly total to your selected payment method each monthly billing cycle until cancellation takes effect. A calendar month is not necessarily 30 days; the provider's billing schedule determines the next date, including month-end adjustments. The schedule and subscription status are available through the support management service. There is no minimum number of future renewals or cancellation fee. A failed payment may be retried for the same billing obligation, or require authentication, as explained in the payment notices. We do not change your agreed recurring amount merely because this page or a provider's fees change.

Management and cancellation: For Stripe support, use the support management link provided on the support page or in payment-related messages to open Stripe's email-authenticated Customer Portal. You can manage the available payment details, review payment history, and cancel monthly support. Cancellation ends the subscription when confirmed and stops new future billing cycles. It does not automatically reverse a payment already completed or in processing. Uninstalling Floorp, deleting browser data, closing a tab, or requesting deletion of personal information does not by itself cancel the subscription. If the portal is unavailable, you cannot access it, or it shows no subscription or the wrong subscription, do not create or change another subscription; contact contact@floorp.app so we can verify the request and identify the correct record before helping stop it. You do not need to create a Floorp account to request cancellation.

Changing an amount: To change an existing monthly amount or an optional additional amount, contact contact@floorp.app. We confirm the new total and when it will apply before processing your requested change. Do not create another subscription merely to change the amount: separate subscriptions can result in separate charges. A new application does not automatically cancel an existing Stripe or GitHub sponsorship.

Optional processing-cost contribution: Floorp Projects does not add a separate processing surcharge at launch. Your card issuer may apply currency-conversion or other charges under its own terms. Any future optional processing-cost contribution requires separate approval, clear display of the total, and your explicit choice before payment.

Refunds and incorrect charges: Cancelling monthly support does not automatically refund earlier contributions or create a prorated refund. Completed voluntary contributions are generally not refundable solely because you change your mind. However, contact contact@floorp.app promptly about duplicate or incorrect charges, suspected unauthorized payments, cancellation failures, or an accidental amount. We investigate and make appropriate corrections or refunds according to the circumstances and applicable law. Include a payment reference, date, amount, and the email used for payment; do not send a full card number or security code. Any approved refund is normally returned through the original payment method, and posting times depend on the provider. Nothing in this section restricts mandatory refund, cancellation, consumer, or payment-dispute rights.

Payment providers and external sponsorships: Stripe processes direct payments and recurring billing; Floorp Projects remains responsible for its own support terms and inquiries. Available payment methods depend on the payment screen and provider. Your card issuer may apply currency-conversion or other charges under its own terms. GitHub Sponsors and other external platforms have their own application, billing, cancellation, refund, and privacy conditions. Manage those sponsorships on the platform used. We do not automatically migrate or link an external sponsorship to Stripe.

Receipts and tax treatment: A payment confirmation or receipt is not a promise that a contribution qualifies for a charitable deduction or other tax relief, and is not by itself a tax-deductible donation certificate. We do not represent Floorp Projects as a registered charity or nonprofit corporation. Tax treatment depends on the actual transaction and applicable law.

Availability and changes: Payment options are offered only where available and permitted for the recipient and transaction. Publishing these conditions does not announce that every option is already available. If we end the direct monthly-support program, we will arrange to stop its future subscription billing and explain relevant outstanding-payment or refund handling. Changes to these conditions follow section 7; a changed amount or newly introduced paid benefit will not be applied simply through continued browser use.
