Terms of Use

1) Provider

The Services are provided by Ryft LLC ("Ryft", "we", "us").

2) Eligibility

You must be at least 13 years old (or the minimum age required by your jurisdiction) to use the App. If you are using the App on behalf of an organization, you represent that you have authority to bind that organization.

3) License & Restrictions

Subject to these Terms and applicable law, we grant you a personal, non-exclusive, non-transferable, license to use the App for your personal or internal purposes, subject to the termination provisions below. The purchased local Pro features have no subscription term or scheduled expiry.

You must not (and must not attempt to):

• Reverse engineer, decompile, disassemble, or attempt to extract source code, except where permitted by law.
• Circumvent, bypass, disable, interfere with, or attempt to defeat Pro access restrictions or security mechanisms.
• Copy, modify, create derivative works of, distribute, sell, lease, sublicense, or publicly display the App, except as expressly allowed by law.
• Use the App to violate law, infringe rights, or engage in fraud, abuse, or harmful conduct.
• Interfere with the App's operation, including by introducing malware, exploiting vulnerabilities, or attempting unauthorized access.

4) Ownership & Intellectual Property

The App, including its software, user interface, designs, text, graphics, logos, and other content, is owned by Ryft or its licensors and is protected by intellectual property laws. Except for the limited license above, no rights are granted to you.

5) Your Content and Data

Your calculations, history, templates, workspaces, notes, tool inputs and settings are stored locally. You keep ownership of your content. Choose carefully what you import, export or share, and do not use those features to infringe another person's rights.

History keeps up to 1,000 newest entries; older entries are replaced as new ones are added. CSV/JSON/text history export and CSV/JSON import are free. Imports accept files up to 5 MB. These formats transfer history, not a full backup of templates, workspaces or settings. Export important records before they leave the retained history.

Files and content you share may be processed by the destinations you choose. A confirmed refund or revocation does not erase saved App data: ordinary history reading and export remain free, with Free limits applying to workspaces and new content.

6) Free, One-Time Pro, Billing and Refunds

6.1 Free and Pro features

Free includes calculations, undo/redo, all three memory slots, all retained history up to 1,000 entries, ordinary history import/export, two workspaces including Main, three saved templates, keypad customization, accessibility settings and six tools: Unit Converter, Tip Calculator, Visual Egg Timer, Discount Calculator, Date Calculator and Notes.

Mobile Pro expands the total to up to eight workspaces and 1,000 saved templates, unlocks all 17 current tools and extra themes, and adds formatted PDF history reports. Both Free and Pro are ad-free. Feature availability can depend on platform and supported App version; the in-app offer identifies the features sold to you.

6.2 One-time payment and included updates

Pro is a single non-consumable in-app purchase, not a subscription. There is no automatic renewal or recurring charge. The relevant app store displays the local price, currency and applicable taxes before confirmation. You may continue using Free without buying Pro.

The purchase provides permanent access to the purchased local Pro features, with regular updates included. Those features will not be moved behind a subscription. It does not include every future product or any separately offered cloud service. This is not a promise of perpetual maintenance, support for every future operating system, or unlimited storage; mandatory consumer rights remain unaffected.

6.3 Local verification, offline use and restoration

Android payment is processed through Google Play. The App checks Google's purchase signature on your device against the Ryft Calc public licensing key and acknowledges completed purchases through Google Play. A Ryft account or Ryft verification server is not required.

After verification, purchase proof is cached in platform secure storage where supported, so purchased local features work offline without a daily online check. The cached signature is checked on app startup.

Use Restore Purchases with the same Google Play account after reinstalling or changing devices. Connect to Google Play for restoration on a new device. Purchases belong to their original store; cross-store access and Ryft account linking are not included. The iPhone version is planned.

When the App starts, resumes or restores purchases, it queries Google Play Billing. Query failures or an unavailable internet connection do not remove previously verified access. A successful query while internet connectivity is available can remove paid access if Pro is no longer in the account's owned-purchase list, including after revocation or a store-account change. Google Play can return cached results, so refunds and revocations are not detected immediately or while offline. Saved content is retained as described in Section 5.

6.4 Refunds and support

Refund eligibility and procedures depend on your store, purchase circumstances and applicable law. See Google Play refunds or Apple refund requests. You can also ask Ryft for help through our contact email (click to reveal).

We do not exclude statutory withdrawal, conformity or refund rights. For EU/EEA/UK consumers, see Section 14. Refund or revocation does not delete saved content; Free access and ordinary history export remain available as described in Section 5.

7) Third-Party Services and Links

The App may integrate with or link to third-party services (for example billing providers) and may open external links. Third parties are governed by their own terms and policies. We are not responsible for third-party services, content, availability, security, or practices.

8) Disclaimers

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE".

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

The App is a general-purpose calculator. You are responsible for verifying results. You must not rely on the App as the sole basis for decisions that may involve risk (including financial, medical, legal, safety-critical, or engineering decisions).

We do not guarantee that the App will be uninterrupted, error-free, secure, or available at all times, or that defects will be corrected.

EU/EEA/UK users: Nothing in this Section 8 affects your statutory rights under applicable consumer protection laws, including the right to conformity of digital content under EU Directive 2019/770 or similar national laws. If the App does not conform to these Terms or is defective, you may have remedies under applicable law that cannot be excluded.

9) Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, RYFT WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, OR REVENUE, ARISING OUT OF OR RELATED TO YOUR USE OF (OR INABILITY TO USE) THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN ALL CASES OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE APP WILL NOT EXCEED THE AMOUNT YOU PAID FOR THE RELEVANT APP OR PRO PURCHASE (IF ANY). THIS DOES NOT LIMIT LIABILITY OR CONSUMER REMEDIES THAT CANNOT LAWFULLY BE LIMITED.

Some jurisdictions do not allow certain limitations of liability or exclusion of implied warranties; in that case, the above limitations apply only to the maximum extent permitted by applicable law.

EU/EEA/UK users: Nothing in this Section 9 excludes or limits our liability for: (a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; (c) any liability that cannot be excluded or limited under applicable law, including consumer protection laws. For EU/EEA/UK consumers, statutory warranty rights and remedies under EU Directives 2019/770 and 2019/771 (or national implementations) cannot be waived.

10) Indemnification

To the maximum extent permitted by law, you agree to indemnify, defend, and hold harmless Ryft and its officers, managers, employees, contractors, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising from or related to: (a) your use of the App, (b) your content, exports, imports, or shares, (c) your violation of these Terms or applicable law, or (d) your infringement of any third-party rights.

11) Copyright / DMCA

If you believe content related to the App infringes your copyright, please send a notice to contact email (click to reveal) with sufficient detail to identify the work and the alleged infringement. We may remove or disable access to allegedly infringing material where required.

12) Termination

We may suspend or terminate your access to the App if you materially violate these Terms, where permitted by law. You may stop using the App at any time by uninstalling it.

13) Dispute Resolution & Arbitration Agreement (U.S. Users Only)

13.1 Informal resolution first (Notice of Dispute)

Before starting arbitration or a court proceeding, you agree to send a written Notice of Dispute to email (click to reveal) (subject line: "Notice of Dispute") or by mail to Ryft LLC, 30 N Gould St Ste R, Sheridan, WY 82801, that includes: (a) your name, (b) the email address associated with your device/account (if any), (c) a description of the dispute, (d) the relief you seek, and (e) sufficient information for us to identify the relevant product and transaction (if applicable). We will attempt to resolve the dispute informally within 60 days of receiving your Notice.

13.2 Agreement to arbitrate

If a dispute is not resolved through informal resolution, you and Ryft agree that, to the maximum extent permitted by law, any dispute, claim, or controversy arising out of or relating to the App or these Terms will be resolved by binding individual arbitration, rather than in court, except as set forth in Section 13.3.

13.2.1 Delegation

The arbitrator (and not a court) will have exclusive authority to resolve any dispute relating to the interpretation, applicability, enforceability, or formation of this arbitration agreement, except that a court will decide the enforceability of the class action waiver.

13.3 Exceptions

• Small claims: Either party may bring an individual claim in small claims court (if eligible) in lieu of arbitration.
• Intellectual property and security: Either party may seek injunctive or equitable relief in court to prevent or stop (a) infringement or misappropriation of intellectual property, or (b) circumvention of Pro access restrictions, fraud, unauthorized access, or security breaches.

13.3.1 Venue for court proceedings (where arbitration does not apply)

To the extent a dispute is properly brought in court under Section 13.3, you and Ryft agree to submit to the exclusive jurisdiction of the state and federal courts located in Wyoming, USA, and waive any objection to venue or inconvenient forum, except where applicable law provides non-waivable rights.

13.4 Arbitration provider and rules

The arbitration will be administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules (as applicable), available at adr.org. If AAA is unavailable to arbitrate, the parties will agree on an alternative reputable arbitration provider. If the parties cannot agree, a court of competent jurisdiction may appoint an arbitrator.

13.5 Arbitration location, format, and language

The arbitration will be conducted in English by a single arbitrator. For consumers, the hearing may be held in the U.S. county (or parish) where you reside, unless you and Ryft agree otherwise, and may be conducted by video/phone or on written submissions when appropriate.

13.6 Arbitration fees and costs

Payment of filing, administration, and arbitrator fees will be governed by the applicable AAA Consumer Arbitration Rules and applicable law. If you are a consumer, Ryft will pay the AAA fees that exceed what you are required to pay under the AAA Consumer Arbitration Rules, to the extent required by those rules or applicable law. Each party will pay its own attorneys' fees and costs unless the arbitrator awards attorneys' fees and costs under applicable law.

13.7 Individual relief only; class action waiver

YOU AND RYFT AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, REPRESENTATIVE, OR PRIVATE ATTORNEY GENERAL PROCEEDING.

THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS AND MAY NOT OTHERWISE PRESIDE OVER ANY FORM OF A REPRESENTATIVE OR CLASS PROCEEDING.

13.8 Mass arbitration / batch proceedings

To increase efficiency, if 25 or more similar arbitration demands are filed against Ryft by or with the assistance of the same law firm, group of law firms, or organizations, within a reasonably short period of time and raising similar issues, the parties agree to administer them in batches of up to 25 demands at a time. The parties will work with the AAA to implement this batching process in a manner intended to be consistent with the AAA's consumer procedures and applicable law, including reasonable coordination of filing/administration fees for later batches so they become due only as those later batches are processed.

13.9 Jury trial waiver

IF FOR ANY REASON A CLAIM PROCEEDS IN COURT RATHER THAN ARBITRATION, YOU AND RYFT WAIVE ANY RIGHT TO A JURY TRIAL TO THE MAXIMUM EXTENT PERMITTED BY LAW.

13.10 Opt-out

You may opt out of the arbitration and class-action waiver provisions by sending an email to email (click to reveal) or a letter to Ryft LLC, 30 N Gould St Ste R, Sheridan, WY 82801 within 30 days of first accepting these Terms, stating your name, the App name, and your intent to opt out. Opting out will not affect any other provisions of these Terms.

13.11 Governing law

To the maximum extent permitted by law, these Terms are governed by the laws of the State of Wyoming, USA, without regard to conflict of law principles. The Federal Arbitration Act (FAA) governs the interpretation and enforcement of this arbitration agreement.

13.12 Limitation period

To the maximum extent permitted by law, any claim must be brought within one (1) year after the events giving rise to the claim, or it is permanently barred, unless applicable law prohibits such a limitation.

13.13 Severability and survival (arbitration)

If any portion of this Section 13 is found to be unenforceable, the remainder will remain in effect. If the class action waiver is found unenforceable, then the arbitration agreement will not apply to the class claim. This Section 13 survives termination of these Terms.

14) Special Provisions for EU/EEA/UK Users

If you are a consumer located in the European Union (EU), European Economic Area (EEA), or United Kingdom (UK), the following provisions apply in addition to or instead of certain provisions above:

14.1 Governing law and jurisdiction

Governing law: These Terms are governed by the laws of your country of residence, to the extent required by mandatory consumer protection laws (including EU Directive 93/13/EEC on unfair contract terms and Regulation (EU) 2017/2394 on consumer protection cooperation).

Jurisdiction: You may bring legal proceedings in the courts of your country of residence. We may bring proceedings only in the courts of your country of residence. This does not affect your right to bring proceedings in the courts of Wyoming, USA, if you choose to do so.

14.2 Arbitration does not apply

Section 13 (Dispute Resolution & Arbitration Agreement) does NOT apply to EU/EEA/UK consumers. You retain all rights to bring disputes in court and to participate in class or collective actions as provided by your national laws.

14.3 Withdrawal rights for digital purchases

EU/EEA and UK consumers may have a 14-day right to withdraw from a distance purchase, subject to applicable national law and exceptions for digital content.

For paid digital content supplied immediately, loss of the withdrawal right requires the conditions set by applicable law, including your prior express consent to immediate supply, express acknowledgment of losing the right, and the required confirmation. Simply downloading or using the App, or accepting these Terms, does not by itself waive the right.

To exercise an applicable right, use the store's refund process or contact Ryft through our contact email (click to reveal). Store policies do not remove mandatory consumer rights.

14.4 Conformity and statutory remedies

Applicable consumer law may give you rights concerning the conformity of digital content, required updates and remedies such as correction, price reduction or termination and refund. The relevant conditions and periods depend on your country and the type of supply. Nothing in these Terms excludes or shortens mandatory rights or remedies.

14.5 Unfair contract terms

Under EU Directive 93/13/EEC, any term in these Terms that is found to be unfair under applicable consumer protection laws will not be binding on you. The remainder of these Terms will remain in effect.

14.6 Consumer redress

The EU Online Dispute Resolution platform closed on 20 July 2025 and is no longer a complaint channel. The European Commission's consumer redress information explains current alternatives, including dispute-resolution bodies and the European Consumer Centres Network.

You may contact us first for help. This does not prevent you from using a competent dispute-resolution body, consumer authority or court where available under applicable law.

14.7 Consumer protection authorities

You have the right to file complaints with your local consumer protection authority regarding these Terms or our Services. Contact information for EU/EEA consumer authorities is available from your national government or the European Consumer Centre Network.

15) Miscellaneous

15.1 Changes

We may update the App and these Terms. The date above identifies this version. We will give notice of material changes where required by law. Changes do not convert your one-time purchase into a subscription or remove the purchased local Pro features to sell them back to you. Mandatory consumer rights continue to apply.

15.2 Severability

If any provision of these Terms is held invalid or unenforceable, the remaining provisions will remain in full force. If the class action waiver is found unenforceable, then the arbitration agreement will be null and void to the extent required by law.

15.3 Entire agreement

These Terms constitute the entire agreement between you and Ryft regarding the App and supersede any prior agreements.

15.4 Platform terms

If you downloaded the App from Apple App Store or Google Play, your use of the App is also subject to the platform's applicable terms. Apple and Google are not parties to these Terms and have no obligations regarding the App. To the extent a platform's terms require different provisions, those platform terms control.

15.5 Electronic communications

You agree that notices, disclosures, and other communications that we provide to you electronically (including via the App, email, or posting within the Services) satisfy any legal requirement that such communications be in writing.

15.6 Export controls and sanctions

You may not use, export, re-export, or transfer the Services except as authorized by United States law, the laws of the jurisdiction where you use the Services, and any other applicable laws and regulations. In particular, the Services may not be used or made available (a) in any U.S.-embargoed country or region, or (b) by anyone on U.S. government restricted parties lists.

15.7 Force majeure

Ryft is not liable for any delay or failure to perform resulting from causes outside its reasonable control, including acts of God, natural disasters, labor disputes, war, terrorism, civil unrest, network or power failures, or governmental actions.

15.8 Assignment

You may not assign or transfer these Terms (or any of your rights or obligations) without our prior written consent. We may assign these Terms in connection with a merger, acquisition, corporate reorganization, or sale of assets.

15.9 No waiver

A failure by Ryft to enforce any provision of these Terms is not a waiver of our right to do so later.

15.10 Apple-specific terms (iOS/iPadOS)

If you use the App on an Apple-branded product, you acknowledge that these Terms are between you and Ryft only, not Apple, and that Apple is not responsible for the App. Apple has no obligation to furnish any maintenance or support services. To the maximum extent permitted by law, Apple will have no warranty obligation with respect to the App. Apple is a third-party beneficiary of these Terms and may enforce these Terms against you as a third-party beneficiary.

15.11 Survival

Sections that by their nature should survive termination (including Sections 4, 8–11, 13, 14, and 15) will survive.
