Terms of Use & End User License Agreement

These Terms become a contract only when you affirmatively accept them through an app, account, purchase, or other interface that clearly states your action constitutes acceptance. Merely viewing the public website does not make a visitor a party to any provision of these Terms, including arbitration, a liability limit, or indemnity. Website visitors remain responsible for obeying applicable law and respecting LogNormal’s intellectual-property rights.

Only an adult with legal capacity may accept these Terms. An adult who affirmatively accepts them in the adult’s own name—whether to use LogNormal personally or to authorize another learner—is the “Contracting Adult.” For a minor’s use, the Contracting Adult must be a parent or legal guardian with legal capacity and authority, and the minor is an “Authorized Learner.” An Authorized Learner is not the purchaser, account holder, or contracting party unless an explicit release flow and applicable law establish otherwise. Whether a Contracting Adult can agree to a provision concerning a minor’s own claim is determined by applicable law; these Terms do not assume authority the law does not provide. An organization may use LogNormal only under a separate written agreement. Do not use the LogNormal Product if you do not agree.

LogNormal is educational mathematics software for learners from age 5 through adult. It provides ways to inspect, express, and apply mathematical ideas. It is not a school, accredited course, testing authority, or substitute for a teacher’s or other qualified professional’s judgment.

Learning depends on many circumstances outside LogNormal’s control. We do not guarantee a grade, score, placement, admission decision, curriculum outcome, or other particular result.

Subject to these Terms, LogNormal grants the Contracting Adult a limited, non-exclusive, non-transferable, non-sublicensable license to install and use the Licensed Application on Apple-branded products that the Contracting Adult owns or controls, and as otherwise permitted by Apple’s Usage Rules, including any applicable Family Sharing or volume-purchase rules. The Contracting Adult and Authorized Learners may use the LogNormal Product for lawful personal or household educational purposes. The Licensed Application is licensed, not sold, and no rights are granted except those expressly stated.

LogNormal and its licensors retain all rights in the software, curriculum, designs, text, audiovisual material, trademarks, and other content supplied through the LogNormal Product. You may not copy, sell, sublicense, distribute, publicly perform, create derivative works from, scrape, or commercially exploit them except where applicable law expressly permits it. Restrictions on reverse engineering apply only to the extent permitted by law and Apple’s applicable terms.

LogNormal is intended for a broad audience of learners from age 5 through adult and is not offered in Apple’s Kids Category. Under the approved launch design, a learner under 13 uses a guardian-managed profile and does not receive independent credentials or provide payment details. Teen account self-management is available only where the learner meets the applicable privacy threshold; unresolved eligibility fails closed. Final release availability remains subject to release qualification.

Account self-management is not the same as legal capacity to purchase a subscription or accept arbitration, indemnity, liability limits, or other contractual terms. For a minor’s use, the parent or legal guardian who satisfies Section 1 is the Contracting Adult; the minor is an Authorized Learner unless the release flow and applicable local law expressly establish otherwise.

An adult who creates or manages a learner profile must provide accurate eligibility information, use the profile only for an authorized learner, and review the Privacy Policy. Paying for a subscription does not by itself grant access to another person’s learning records. Do not use LogNormal as a school or institutional student-record system unless LogNormal has entered a separate written agreement for that use.

You are responsible for protecting your credentials and for activity you authorize. Tell us promptly through Support if you suspect unauthorized access. You may not sell, transfer, or share account credentials outside the family or account relationships the product expressly supports.

The current reviewed prelaunch build does not enable new public account creation, public subscriptions, or public account controls. A device retaining a session from an earlier account-enabled beta may still contact LogNormal’s account service and synchronize pending progress when the app starts. Review Account Deletion if you want an earlier account removed.

Features described as planned, coming at launch, or under development are not promises that a feature will ship on a particular date or in a particular form.

The website does not sell the app, process payment cards, or activate a subscription. If LogNormal offers a paid auto-renewing subscription, the transaction will occur through Apple’s App Store. The purchase screen will display the actual product, price, currency, billing period, renewal terms, included access, and any trial or offer before confirmation.

An auto-renewing subscription continues until it is canceled through the Apple account used to purchase it. Apple controls charging, tax, currency conversion, renewal, cancellation timing, billing recovery, and refund processing under Apple’s terms and applicable law. Deleting the app or a LogNormal learner profile does not itself cancel an Apple subscription. The app must provide a way to restore eligible purchases and reach Apple’s subscription-management tools before the paid launch is release-qualified.

If a price changes, Apple will provide any notice or consent process it requires. Cancellation affects future renewal as Apple explains during the transaction; it does not retroactively refund charges except where Apple or applicable law provides otherwise. Nothing here limits a non-waivable cancellation, refund, or consumer right.

Founding Families is the planned first paid customer cohort around the public App Store launch. The website currently describes $14.99 USD per month as the working founding price and $17.99 USD per month as the planned broader price. These are plans until the corresponding App Store product is configured and offered.

The founding price does not by itself create access, eligibility, a vested entitlement, or a promise that a price will remain unchanged permanently or for life. The App Store offer presented before purchase controls the actual price and subscription terms.

You may not misuse the LogNormal Product; bypass or probe security or access controls; interfere with operation; introduce malware; automate access in a way that burdens the LogNormal Product; impersonate another person; obtain another learner’s information without authority; submit unlawful, harmful, or infringing material; harass another person; or use support, privacy, or deletion channels fraudulently or abusively.

You may not use the LogNormal Product to develop, train, benchmark, or improve a competing commercial product unless LogNormal gives written permission. This restriction does not prohibit conduct protected by applicable law.

You retain any rights you have in learner-authored mathematical work. You give LogNormal a limited license to host, process, transmit, reproduce, and display that work only as needed to operate the feature you choose, maintain authorized progress, protect the LogNormal Product, and meet legal obligations. This license ends when the information is deleted, except for limited copies retained as described in the Privacy Policy or where deletion is technically or legally unavailable.

If you voluntarily send ideas or feedback, you permit LogNormal to use them to evaluate and improve its products without restriction or compensation. Do not send confidential information through feedback.

This prelaunch draft is structured as a candidate custom end-user license agreement so one coherent contract can govern the Licensed Application, related services, risk allocation, and dispute terms. Before relying on it, LogNormal must obtain qualified review, configure this exact version as the custom EULA in App Store Connect, and capture affirmative acceptance. If the release instead uses Apple’s Standard End User License Agreement, that agreement may govern the Licensed Application and services accessible from or purchased within it; these Terms must then be narrowed and reconciled before release rather than layered over the same subject matter.

Apple’s App Store and Media Services terms continue to govern distribution, the Apple account, App Store payment processing, and Apple-provided services. TestFlight builds are also governed by Apple’s TestFlight Terms. Parts of the LogNormal Product may rely on Apple, internet access, device software, or service providers identified in the Privacy Policy. Their services and terms are separate, and LogNormal does not control their availability. You must comply with applicable third-party terms when using the LogNormal Product.

Our handling of information is described in the Privacy Policy. Family-account practices appear in Children & Family Privacy. Available requests and controls are explained under Privacy Choices and Account Deletion. A privacy notice is not contractual consent to collect a child’s information or a waiver of rights or duties imposed by applicable privacy law.

We may maintain, update, replace, suspend, or discontinue parts of the LogNormal Product. We will provide notice when required by law and will not use this section to avoid obligations for a paid period or eliminate a non-waivable consumer remedy.

Pre-release and beta features may be incomplete, change materially, contain errors, or be withdrawn. Do not rely on them for high-stakes educational, safety, legal, medical, or financial decisions.

You may stop using the LogNormal Product at any time. Subscription cancellation and account deletion are separate actions. We may restrict or terminate access if reasonably necessary to address a material breach, fraud, security risk, legal requirement, harm to another person, or risk to the LogNormal Product. Where appropriate and legally required, we will give notice and a reasonable opportunity to cure.

Sections that by their nature should survive—including ownership, payment obligations already incurred, disclaimers, liability limits, indemnity, dispute resolution, and general terms—survive termination.

FOR MATTERS GOVERNED BY THESE TERMS, AND TO THE FULLEST EXTENT PERMITTED BY LAW, THE LOGNORMAL PRODUCT IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITH ALL FAULTS. LOGNORMAL DISCLAIMS EXPRESS, IMPLIED, AND STATUTORY WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, QUIET ENJOYMENT, ACCURACY, AND NON-INFRINGEMENT.

We do not warrant that the LogNormal Product will be uninterrupted, secure, error-free, compatible with every device, or free from harmful components, or that stored information will never be lost. No oral or written statement creates a warranty unless expressly identified as one by LogNormal. Some jurisdictions do not allow certain disclaimers, so this section applies only to the extent permitted by law.

FOR CLAIMS GOVERNED BY THESE TERMS, AND TO THE FULLEST EXTENT PERMITTED BY LAW, LOGNORMAL AND ITS MEMBERS, MANAGERS, EMPLOYEES, CONTRACTORS, AND AGENTS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, GOODWILL, USE, OR DATA, ARISING FROM OR RELATED TO THE LOGNORMAL PRODUCT, EVEN IF ADVISED THAT SUCH DAMAGES WERE POSSIBLE.

TO THE FULLEST EXTENT PERMITTED BY LAW, LOGNORMAL’S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ASSERTED BY ONE CONTRACTING ADULT, TOGETHER WITH CLAIMS ASSERTED BY ANY AUTHORIZED LEARNER WHOSE USE THAT ADULT AUTHORIZED, AND ARISING FROM THE SAME OR RELATED EVENTS, WILL NOT EXCEED THE GREATER OF (A) US $100 OR (B) THE TOTAL AMOUNT THAT CONTRACTING ADULT PAID FOR THE LOGNORMAL PRODUCT THROUGH THE APP STORE DURING THE 12 MONTHS IMMEDIATELY BEFORE THE EARLIEST EVENT GIVING RISE TO THOSE CLAIMS.

These limitations apply regardless of the form of action and even if a remedy fails of its essential purpose. They do not exclude or limit liability for fraud, willful misconduct, gross negligence, death or personal injury, or privacy, security, or child-safety obligations where applicable law does not permit that exclusion or limitation. They do not limit any other warranty, remedy, liability, or consumer right that cannot lawfully be limited.

To the extent permitted by law, a Contracting Adult will indemnify LogNormal against a third-party claim arising from material that adult knowingly submits in violation of another person’s rights, that adult’s intentional unlawful misuse of the LogNormal Product, or that adult’s material breach of Section 8. Covered amounts are limited to reasonable, documented losses and outside legal fees incurred in defending the covered claim, plus judgments finally awarded and settlements the adult approved. This does not apply to ordinary intended use, to an amount attributable to LogNormal’s negligence or wrongdoing, or solely because an Authorized Learner used LogNormal as intended. LogNormal will give prompt reasonable notice, may control the defense with reasonably selected counsel, and will keep the Contracting Adult reasonably informed. LogNormal will not settle a claim in a way that requires the Contracting Adult to pay money, admit fault, or undertake a non-monetary obligation without that adult’s prior written consent, which will not be unreasonably withheld. The adult has no duty to provide or fund a defense and no obligation to reimburse defense costs as they are incurred. Any reimbursement obligation becomes due only after a final non-appealable judgment determines that the claim is covered or the adult approves a settlement that resolves the claim.

The Federal Arbitration Act governs Section 17. For other matters within these Terms’ scope, Wyoming law governs without regard to conflict-of-law principles, except that mandatory consumer protections of your place of residence continue to apply. Except for a small-claims proceeding permitted by Section 17, any court proceeding not subject to arbitration must be brought in a court of competent jurisdiction in Wyoming unless applicable law gives you the right to proceed elsewhere. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

These Terms are between you and LogNormal, not Apple. LogNormal, not Apple, is solely responsible for the Licensed Application and its content. These Terms may not provide usage rules for the Licensed Application that conflict with Apple’s applicable Media Services Terms.

LogNormal is solely responsible for providing maintenance and support for the Licensed Application as specified in these Terms or required by applicable law. Apple has no obligation to provide maintenance or support.

LogNormal is solely responsible for any product warranties that have not been effectively disclaimed. If the Licensed Application fails to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price for the Licensed Application, if any. To the maximum extent permitted by law, Apple has no other warranty obligation. As between Apple and LogNormal, LogNormal is solely responsible for all other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to an applicable warranty.

As between Apple and LogNormal, LogNormal—not Apple—is responsible for addressing any claim by you or a third party relating to the Licensed Application or your possession or use of it, including product-liability claims; claims that it fails to conform to an applicable legal or regulatory requirement; and claims under consumer-protection, privacy, or similar law. These Terms do not limit liability beyond what applicable law permits.

If a third party claims that the Licensed Application or your possession and use of it infringes that party’s intellectual-property rights, LogNormal—not Apple—is solely responsible for the investigation, defense, settlement, and discharge of that claim.

You represent and warrant that you are not located in a country subject to a United States government embargo or designated by the United States government as supporting terrorism and are not listed on a United States government prohibited- or restricted-party list. You must comply with applicable third-party agreements when using the Licensed Application.

Apple and its subsidiaries are third-party beneficiaries of these Terms. Upon your acceptance of these Terms, Apple will be deemed to have accepted that right and may enforce these Terms against you as a third-party beneficiary.

These Terms and any purchase terms presented at confirmation are the entire contractual agreement concerning their subject matter. The Privacy Policy is a notice of data practices and rights; it is not incorporated as a contractual warranty, consent, or waiver, though this sentence does not limit any duty or remedy imposed by applicable law. If a provision of these Terms is unenforceable, it will be enforced to the maximum lawful extent and the remainder will continue, subject to Section 17’s specific severability rule. Failure to enforce a provision is not a waiver.

You may not assign these Terms without our consent. LogNormal may assign them in connection with a merger, acquisition, financing, reorganization, or sale of assets, provided the successor assumes the applicable obligations. LogNormal is not liable for delay caused by circumstances beyond its reasonable control, but this does not excuse payment, refund, security, privacy, or other duties that law makes non-waivable.

We may update these Terms as the product or law changes. The effective date identifies the current version. Material changes will receive notice and renewed acceptance when required; they will not retroactively change a dispute that arose before the update.

The receiving inbox is available below. Receipt of ordinary email does not establish that legal-notice, arbitration opt-out, acknowledgement, retention, or escalation procedures are operational. This remains a prelaunch draft until the required acceptance and dispute-handling processes are verified.
