Welcome to Fluo ("Fluo," "the app," "we," "us," or "our"). These Terms of Use ("Terms") govern your access to and use of the Fluo mobile application and related services (collectively, the "Service"). By downloading, installing, or using Fluo, you agree to be bound by these Terms. If you do not agree, do not use the Service.
You must be at least 13 years old to use Fluo. If you are under the age of majority in your jurisdiction, you may only use the Service with the involvement of a parent or legal guardian who agrees to these Terms on your behalf.
Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use Fluo on Apple devices that you own or control, solely for your personal, non-commercial use.
This license is granted by us and is in addition to the standard Apple Licensed Application End User License Agreement, which also applies to your use of Fluo. In the event of any conflict between these Terms and the Apple EULA, these Terms control with respect to the Fluo-specific provisions.
Fluo offers auto-renewing subscriptions that unlock access to premium features ("Pro"). Subscription details — including price, length, and benefits — are displayed in the app before you complete a purchase. By purchasing a subscription, you acknowledge and agree to the following:
All purchases are processed by Apple and are subject to Apple's refund policy. We do not directly process refunds. To request a refund, please visit reportaproblem.apple.com.
We reserve the right to change subscription prices at any time. Any price changes will take effect at the start of the next subscription period after the date of the price change. Where required by law, we will notify you in advance of any price change and give you the opportunity to cancel before the change takes effect.
Fluo provides AI-powered language learning features (chat tutoring, voice transcription, text-to-speech, corrections, and suggestions) through third-party AI service providers, including but not limited to Google (Gemini), Groq, Fish Audio, and DeepInfra (collectively, "AI Providers").
You acknowledge and agree that:
You agree not to:
We reserve the right to investigate and take appropriate action against anyone who, in our sole discretion, violates these Terms — including suspending or terminating their access to the Service.
"User Content" means any text, voice recordings, custom instructions, saved phrases, or other material you provide to or generate through the Service. You retain ownership of your User Content. By using the Service, you grant us a worldwide, non-exclusive, royalty-free license to process your User Content solely for the purpose of operating, providing, and improving the Service — including transmitting it to AI Providers as necessary to fulfill your requests.
We do not claim ownership of your User Content, and we do not use your User Content to train AI models.
Fluo, including its design, branding, source code, and original content, is owned by us and is protected by copyright, trademark, and other intellectual property laws. Except for the limited license granted in Section 2, nothing in these Terms transfers any intellectual property rights to you.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ACCURACY OF AI-GENERATED OUTPUT.
WE DO NOT WARRANT THAT:
Your use of the Service is at your sole risk.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF (OR INABILITY TO USE) THE SERVICE.
OUR TOTAL LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) FIFTY U.S. DOLLARS ($50.00).
Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above limitations may not apply to you.
You agree to indemnify, defend, and hold harmless Fluo and its developers, affiliates, and agents from any claims, damages, losses, liabilities, and expenses (including reasonable legal fees) arising out of or related to: (a) your use of the Service; (b) your violation of these Terms; (c) your violation of any rights of another party; or (d) your User Content.
We may suspend or terminate your access to the Service at any time, with or without notice, for any reason — including if we believe you have violated these Terms. Upon termination, your right to use the Service immediately ceases.
You may stop using the Service at any time by deleting the app from your device. Note that deleting the app does not cancel any active subscriptions; you must cancel through your Apple ID settings.
The Service relies on third-party services to function, including Apple (App Store and in-app purchases), RevenueCat (subscription management), Google (Gemini API), Groq (speech transcription), Fish Audio (text-to-speech), DeepInfra (text-to-speech), and Cloudflare (infrastructure). Your use of the Service is also subject to these providers' own terms and privacy policies. We are not responsible for the acts, omissions, or content of any third-party service.
Your use of the Service is also governed by our Privacy Policy, which describes how we collect, use, and share information. By using the Service, you consent to the practices described in the Privacy Policy.
We may modify these Terms at any time. If we make material changes, we will update the "Last updated" date at the top of this document and, where appropriate, provide additional notice within the app. Your continued use of the Service after changes take effect constitutes your acceptance of the revised Terms.
These Terms are governed by and construed in accordance with the laws of the United States, without regard to its conflict of laws principles. Any disputes arising out of or relating to these Terms or the Service shall be resolved exclusively in the state or federal courts located in the United States, and you consent to the personal jurisdiction of such courts.
You acknowledge that these Terms are between you and us, not Apple, and that Apple is not responsible for the Service or its content. Apple has no obligation to furnish any maintenance and support services with respect to the Service. In the event of any failure of the Service to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the app to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the Service.
Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary thereof.
If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary so that the remaining Terms remain in full force and effect.
These Terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding the Service and supersede any prior agreements.
