Terms of Use for Recif

Last updated: July 20, 2026
Effective date: July 20, 2026

Welcome to Recif. These Terms of Use ("Terms") are a binding agreement between you and Pristn Technologies LLC, a limited liability company organized in the State of Nebraska, United States ("Pristn", "we", "us", or "our"), and govern your access to and use of the Recif mobile application and related services (together, the "Service").

Please read these Terms carefully. By creating an account or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

The Service is available to users in the United States, Canada, Brazil, and other countries in Latin America where it is offered.

1. Definitions

  • "Service" means the Recif app, its features, and related services operated by Pristn.
  • "Account" means the account you create to use the Service.
  • "Your Content" means anything you submit, create, upload, or enter through the Service, including tanks, water-test readings, target ranges, maintenance tasks, livestock records, notes, photos, voice notes, and your profile information.
  • "Reef Stability Score" means the informational score, along with the charts and trends, that the Service derives from the readings you enter.
  • "Recif Pro" means our paid subscription described in Section 9.

2. Eligibility

You must be at least 13 years old to use the Service. If you are between 13 and the age of majority where you live, you may use the Service only with the consent and supervision of a parent or legal guardian, where your local law requires it. By using the Service, you represent that you meet these requirements and that you have the legal capacity to enter into these Terms. The Service is not available to anyone previously removed from the Service by us.

3. Your account

  • Registration. You can create an Account with an email and password, or by using Sign in with Apple or Sign in with Google. You agree to provide accurate information and to keep it up to date.
  • Security. You are responsible for keeping your credentials confidential and for all activity under your Account. Notify us promptly at contact@pristntechnologies.com if you suspect unauthorized use.
  • One person, one account. You may not maintain accounts through automated means or use another person's account without permission.

4. License to use the Service

Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use the Service on devices you own or control, for your personal, non-commercial use. We reserve all rights not expressly granted.

5. Nature of the Service; no aquarium, veterinary, or professional advice

Recif is a tool for logging your aquarium's water parameters, tracking livestock, scheduling maintenance, and watching trends over time. The Reef Stability Score, target ranges, charts, and reminders are informational aids based only on the readings and information you enter. They are estimates and conveniences, not guarantees.

Recif is not a substitute for your own judgment as an aquarist, and it is not aquarium, veterinary, medical, or other professional advice. The Service does not test your water, dose your tank, control your equipment, or diagnose problems. Readings can be entered incorrectly, test kits and equipment have their own error, and a score or reminder can be wrong or delayed. Decisions about your aquarium, your equipment, and the animals in it remain entirely yours.

To the fullest extent permitted by law, we are not responsible for any loss of or harm to livestock, corals, or other animals, or for tank crashes, equipment failure, water-quality problems, property damage, or any other outcome, arising from your use of or reliance on the Service. You use the Service and its guidance at your own discretion and risk, and you should keep your own independent means of monitoring and maintaining your aquarium.

6. Your content

  • You own your content. You retain all rights you have in Your Content. We do not claim ownership of it.
  • License you grant to us. To operate the Service, you grant Pristn a worldwide, non-exclusive, royalty-free license to host, store, reproduce, modify (for technical purposes such as resizing images), and display Your Content, solely to provide and maintain the Service, including storing it and syncing it back to you across your own devices. This license ends when you delete the content or your Account, except for copies retained in routine backups for a limited time, and except as needed to comply with law.
  • Your responsibility. You are solely responsible for Your Content and represent that you have the rights necessary to store it and that it does not violate these Terms or any law or third-party right.
  • Export. You can export your readings, livestock, and maintenance log as a CSV file at any time from within the App, and you can delete Your Content at any time.

7. Acceptable use

You agree not to, and not to allow anyone else to:

  • Use the Service for any unlawful, harmful, fraudulent, or abusive purpose.
  • Upload viruses, malware, or any code designed to disrupt or harm.
  • Attempt to gain unauthorized access to the Service, other accounts, or our systems, or interfere with or overload the Service.
  • Reverse engineer, decompile, or attempt to extract source code, except to the extent this restriction is prohibited by law.
  • Use bots, scrapers, or automated means to access or collect data from the Service.
  • Resell, rent, or commercially exploit the Service without our written permission.
  • Circumvent any usage limit, paywall, or security feature.

We may investigate and take appropriate action, including suspending or terminating accounts, for any violation.

8. Notifications and communications

By using the Service, you agree that we may send you transactional messages necessary to operate it, such as email verification, password resets, security alerts, and account-deletion confirmations. If you enable push notifications, we will send the reminders and alerts you turn on (such as due tasks, test-gap nudges, and Reef Stability Score alerts). You can control notifications in the App and in your device settings.

9. Subscriptions, billing, and refunds

  • Free tier and Recif Pro. The Service offers a free tier and an optional paid subscription called Recif Pro. The free tier lets you track up to 2 tanks and view up to 90 days of chart history. Recif Pro unlocks unlimited tanks, your full reading history, and advanced charts (such as overlays, variance, and correlations). Reminders and maintenance tasks are never behind the paywall. Current limits are shown in the App.
  • Auto-renewing subscription and free trial. Recif Pro is an auto-renewing annual subscription and may include a free trial. If a free trial is offered, it converts to a paid annual subscription unless you cancel at least 24 hours before it ends, and the subscription then renews automatically each year until you cancel. Applicable trial or introductory terms are disclosed at purchase, and unused portions of a free trial are forfeited when you purchase a subscription.
  • Purchases through the app stores. All purchases are processed by the Apple App Store or Google Play through their in-app purchase systems. Prices are shown in the App in your local currency before you confirm. We do not receive or store your full payment card or bank details.
  • Auto-renewal and cancellation. Your account is charged for renewal within 24 hours before the current period ends, unless you cancel at least 24 hours beforehand. You manage and cancel your subscription through your Apple App Store or Google Play account settings, not through us. Deleting the App does not cancel your subscription.
  • Refunds. Payments are generally non-refundable except where required by law. Because purchases are made through the app stores, refund requests are handled under Apple's or Google's policies. For users in jurisdictions with mandatory consumer-protection or cancellation rights (including Brazil, Canada, and other Latin American countries), nothing in these Terms limits those rights.
  • Changes to limits and prices. We may change the free-tier limits or subscription prices. Tanks you have already created are not removed if a free-tier limit changes. For price changes, we will give notice as required, and changes apply to the next billing period; if you do not agree, you may cancel before the change takes effect.

10. Third-party services

The Service relies on third parties (including Apple, Google, RevenueCat, Cloudflare, Expo, and others described in our Privacy Policy) and may link to or interoperate with third-party services. We are not responsible for third-party services, and your use of them is governed by their own terms and privacy policies.

11. Intellectual property

The Service, including its software, design, logos, and the "Recif" name, is owned by Pristn Technologies LLC and protected by intellectual property laws. Except for the license in Section 4, these Terms do not grant you any right in our intellectual property. You may not use our trademarks without our prior written permission.

12. Feedback

If you send us suggestions or feedback, you grant us a perpetual, irrevocable, royalty-free license to use it for any purpose without obligation to you.

13. Privacy

Your use of the Service is also governed by our Privacy Policy, which explains how we handle your information. By using the Service, you consent to that handling.

14. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, ERROR-FREE, THAT SYNC WILL NEVER FAIL, OR THAT DATA WILL NOT BE LOST. YOU USE THE SERVICE AT YOUR OWN RISK.

As described in Section 5, the Reef Stability Score, target ranges, charts, and reminders are informational aids based on the data you enter and are not aquarium, veterinary, or other professional advice. Keep your own backups of anything critical, including by using the CSV export for a copy you control.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you. In that case, our warranties are limited to the minimum extent permitted by law.

15. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, PRISTN TECHNOLOGIES LLC AND ITS OFFICERS, MEMBERS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, GOODWILL, LIVESTOCK, OR OTHER TANGIBLE OR INTANGIBLE LOSSES, ARISING OUT OF OR RELATED TO YOUR USE OF, OR INABILITY TO USE, THE SERVICE.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) TWENTY-FIVE U.S. DOLLARS (USD 25.00).

Some jurisdictions do not allow certain limitations, so some of the above may not apply to you. Nothing in these Terms limits liability that cannot be limited by law, including, for consumers in Brazil, Canada, and other Latin American countries, the mandatory rights granted by applicable consumer-protection law.

16. Indemnification

To the extent permitted by law, you agree to indemnify and hold harmless Pristn Technologies LLC and its officers, members, employees, and agents from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising out of Your Content, your use of the Service, or your violation of these Terms or any law or third-party right.

17. Suspension and termination

  • By you. You may stop using the Service and delete your Account at any time from within the App.
  • By us. We may suspend or terminate your access, with or without notice, if you violate these Terms, if required by law, or to protect the Service or other users. We may also discontinue the Service or any feature.
  • Effect. On termination, your license to use the Service ends. Sections that by their nature should survive (including intellectual property, disclaimers, limitation of liability, indemnification, and dispute resolution) will survive. Account deletion is handled as described in our Privacy Policy.

18. Changes to the Service and these Terms

We may modify the Service or these Terms. If we make material changes to these Terms, we will update the "Last updated" date and provide reasonable notice (such as an in-app message or email). Changes take effect when posted, or on a later date we specify. Your continued use of the Service after changes take effect means you accept the updated Terms. If you do not agree, stop using the Service and delete your Account.

19. Governing law and dispute resolution

19.1 Governing law

These Terms are governed by the laws of the State of Nebraska and applicable federal laws of the United States, without regard to conflict-of-laws rules. This choice of law does not deprive you of the protection of mandatory consumer-protection laws of your country of residence (including, for example, Brazil's Código de Defesa do Consumidor and similar laws in Canada and other Latin American countries).

19.2 Informal resolution

Before filing a claim, you agree to first contact us at info@pristntechnologies.com and try in good faith to resolve the dispute informally. Most concerns can be resolved this way.

19.3 Binding arbitration and class-action waiver (United States users)

This Section 19.3 applies to users located in the United States, to the extent permitted by law.

If we cannot resolve a dispute informally, you and Pristn agree to resolve any dispute arising out of or relating to these Terms or the Service through final and binding arbitration on an individual basis, administered by a recognized arbitration provider under its consumer rules, rather than in court, except that either party may bring an individual claim in small-claims court. You and Pristn waive the right to a jury trial and to participate in a class, collective, or representative action. You may opt out of this arbitration agreement by emailing info@pristntechnologies.com within 30 days of first accepting these Terms. This Section does not apply where prohibited by law.

19.4 Courts and venue

For users outside the United States, or where arbitration does not apply, disputes will be subject to the exclusive jurisdiction of the state and federal courts located in Nebraska, United States, except that consumers may bring claims in the courts of their country of residence where local law gives them that right, and we may bring claims in your country of residence where required.

20. Apple App Store: additional terms

If you download the App from the Apple App Store, the following also applies, and these Terms are between you and Pristn only, not Apple:

  • Apple has no obligation to provide maintenance or support for the App.
  • Apple is not responsible for any product warranties; to the extent any warranty is not effectively disclaimed, Apple may refund the purchase price (if any), and otherwise has no warranty obligation.
  • Apple is not responsible for addressing any claims relating to the App, including product liability, legal or regulatory compliance, or consumer protection claims.
  • Apple is not responsible for the investigation, defense, settlement, or discharge of any third-party intellectual property claim relating to the App.
  • You represent that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
  • Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

21. Google Play: additional terms

If you download the App from Google Play, your use is also subject to the Google Play Terms of Service. To the extent of any conflict between these Terms and the Google Play Terms regarding your use of the App obtained through Google Play, these Terms govern the relationship between you and Pristn, and the Google Play Terms govern your relationship with Google.

22. General

  • Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and Pristn regarding the Service and supersede any prior agreements.
  • Severability. If any provision is found unenforceable, the rest remains in effect, and the unenforceable provision will be limited or removed to the minimum extent necessary.
  • No waiver. Our failure to enforce a provision is not a waiver of our right to do so later.
  • Assignment. You may not assign these Terms without our consent. We may assign them in connection with a merger, acquisition, or sale of assets.
  • Force majeure. We are not liable for delays or failures caused by events beyond our reasonable control.
  • Notices. We may provide notices through the App, by email, or by posting on https://pristntechnologies.com/. You may contact us as set out below.
  • Language. These Terms are provided in English. If we provide a translation, the English version governs in case of conflict, except where your local law requires otherwise.
