Terms of Service — Tutor Flow
Last updated: 2026-09-15
These Terms of Service (“Terms”) constitute a binding agreement between you (“User,” “you,” or “your”) and Native Flow, a trade name of Dante Jamel Wadley Woodbury, a self-employed professional (autónomo) operating in Madrid, Spain (“Company,” “we,” “us,” or “our”), governing your access to and use of the Tutor Flow browser extension (the “Extension” or “Service”).
By installing, accessing, or using the Extension, you agree to be bound by these Terms. If you do not agree to these Terms, you must not install or use the Extension.
1. The Service
Tutor Flow is a browser extension designed for tutors on the Ringle platform, providing scheduling tools, student-tracking features, editor shortcuts, and calendar conflict detection layered on top of the Ringle tutor interface.
Tutor Flow is developed and operated independently of Ringle. It is not affiliated with, sponsored by, or endorsed by Ringle, and any reference to Ringle or its trademarks is solely for the purpose of describing compatibility with the Ringle platform. All trademarks, service marks, and trade names referenced herein are the property of their respective owners.
2. Eligibility
The Service is intended for individuals who are active tutors on the Ringle platform. By using the Service, you represent and warrant that you are at least 18 years of age and have the legal capacity to enter into these Terms. You further represent that you are acquiring and using the Service for purposes related to your trade, business, or profession, and not as a consumer.
3. Subscription and Billing
3.1. The Service is offered on a subscription basis, at the pricing displayed at the time of purchase (currently $6.99 per month or $76.89 per year).
3.2. New subscribers receive a ten (10) day free trial from the date of activation. You will not be charged during the trial period, and you may cancel at any time before it ends at no cost.
3.3. If you do not cancel before the trial period ends, your subscription will begin automatically at the plan you selected, and billing will commence at that time.
3.4. Payments are processed by Creem, our third-party payment processor and merchant of record, which handles billing, applicable taxes (including VAT), and payment security on our behalf. By subscribing, you also agree to Creem’s applicable terms governing payment processing.
3.5. Subscriptions renew automatically at the end of each billing period unless cancelled prior to renewal.
3.6. You may cancel your subscription at any time through the Extension or through the Creem customer portal. Cancellation takes effect at the end of your current billing period — whether monthly or annual — and you will retain access to the Service until that date. No further charges will be made following cancellation.
4. Refunds
The Company does not provide refunds for amounts already billed. Because every new subscription includes the free trial period described in Section 3.2, you are able to evaluate the Service in full before any charge is made. Cancelling after the trial period stops future renewals but does not entitle you to a refund of the current billing period.
5. Acceptable Use
In connection with your use of the Service, you agree that you shall not:
- (a) reverse engineer, decompile, or disassemble the Extension, or otherwise attempt to derive its source code, except to the extent such restriction is prohibited by applicable law;
- (b) resell, sublicense, share, or otherwise make the Service or your subscription available to any third party;
- (c) circumvent, disable, or interfere with any license validation or technical protection measures within the Extension;
- (d) use the Service to scrape, harvest, or otherwise repurpose data — including calendar data — for any purpose beyond the Service’s stated scheduling and conflict-detection functionality;
- (e) use the Service in a manner that violates Ringle’s own platform policies or terms of service; or
- (f) use the Service for any unlawful purpose, or in a manner that interferes with the security, integrity, or normal operation of the Ringle platform.
The Company reserves the right to suspend or terminate your access to the Service for any violation of this Section.
6. Google Account Data
The Extension requests limited, read-only access to your Google Calendar and basic profile information solely to power its calendar conflict-detection feature. The Company’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements. Full details are set out in our Privacy Policy, which is incorporated into these Terms by reference.
7. Intellectual Property
The Extension, including its underlying code, design, and branding, is and remains the exclusive property of the Company. These Terms do not transfer any ownership of the Service to you. Subject to your compliance with these Terms, the Company grants you a limited, non-exclusive, non-transferable, revocable license to use the Extension for its intended purpose.
8. Disclaimer of Warranties
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING, WITHOUT LIMITATION, IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. THE COMPANY DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR COMPATIBLE WITH EVERY CONFIGURATION OF THE RINGLE PLATFORM, WHICH MAY CHANGE INDEPENDENTLY OF THE COMPANY AT ANY TIME.
9. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE COMPANY BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO YOUR USE OF, OR INABILITY TO USE, THE SERVICE — INCLUDING, WITHOUT LIMITATION, LOST INCOME RESULTING FROM SCHEDULING ERRORS OR MISSED CALENDAR CONFLICTS — EVEN IF THE COMPANY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IN NO EVENT SHALL THE COMPANY’S TOTAL LIABILITY ARISING OUT OF THESE TERMS EXCEED THE AMOUNT YOU PAID THE COMPANY IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM. NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW.
10. Indemnification
You agree to indemnify, defend, and hold harmless the Company from and against any claims, liabilities, damages, losses, and expenses, including reasonable legal fees, arising out of or in any way connected with your violation of these Terms or your misuse of the Service.
11. Termination
The Company may suspend or terminate your access to the Service at any time in the event of a violation of these Terms. You may discontinue use of the Service and cancel your subscription at any time in accordance with Section 3.
12. Changes to These Terms
The Company may amend these Terms from time to time. Material changes will be reflected by an updated “Last updated” date and, where required by applicable law, communicated to active subscribers in advance of taking effect. Your continued use of the Service following any such change constitutes your acceptance of the amended Terms.
13. Governing Law and Jurisdiction
These Terms shall be governed by and construed in accordance with the laws of Spain, without regard to its conflict-of-law principles. Any dispute arising out of or relating to these Terms shall be subject to the exclusive jurisdiction of the courts of Madrid, Spain, without prejudice to any mandatory consumer-protection rights you may have under the laws of your country of residence.
14. General Provisions
14.1. Entire Agreement. These Terms, together with the Privacy Policy, constitute the entire agreement between you and the Company with respect to the Service and supersede all prior understandings, whether written or oral.
14.2. Severability. If any provision of these Terms is held invalid or unenforceable, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
14.3. Assignment. You may not assign or transfer these Terms, or any rights or obligations hereunder, without the Company’s prior written consent. The Company may assign these Terms without restriction, including in connection with a merger, acquisition, or sale of assets.
14.4. Waiver. No failure or delay by the Company in exercising any right under these Terms shall constitute a waiver of that right.
