Terms of Service
Effective 29 September 2026
These terms are the agreement between you and rikAI LLC for the rikAI app and this website. They contain a disclaimer of warranties, a limit on our liability, and an agreement to arbitrate disputes individually rather than in court — please read sections 10 to 13.
1 · Agreement
Who this is between
"rikAI", "we" and "us" mean rikAI LLC, a Pennsylvania limited liability company. "You" means the person using the app or the site. "The Service" means the rikAI iPhone app, our websites at rikaillm.com and rikaillm.jp, and anything we serve from it, including optional model and voice downloads and cloud Ask answers.
By installing or using the app, or by using this site, you accept these terms. If you do not accept them, do not use the Service. If you are using rikAI for an organisation, you are agreeing on its behalf and confirming you may do so.
Updated 29 September 2026: these terms clarify cloud permission, device requirements, reader allowances and when local Ask is available. Cloud Ask remains off unless you explicitly allow it.
2 · Licence
What you may do with the app
We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to install and use rikAI on Apple-branded devices you own or control, as permitted by the App Store's Usage Rules — including by other accounts in your Family Sharing group where those rules allow it — for your own purposes — including your own commercial and professional work. You may not sublicense it, rent it out, or sell access to it.
You may not, and may not let anyone else: reverse-engineer, decompile or disassemble the app or the language models it ships with, except where that restriction is void under law you can't waive; extract, redistribute or resell the models, dictionaries or other data files; remove or obscure any attribution or licence notice; circumvent the free-tier limits or the subscription check; or use the app in a way that breaks the law or these terms.
rikAI includes third-party open data and software, listed with its licences under Settings → About → Licenses & credits. Those licences govern those components, and where one conflicts with this section, it wins for that component.
You must comply with any third-party terms that apply to your use of rikAI — your carrier's data plan, for instance. Optional model and voice downloads are large, and any data charges they incur are yours.
3 · Payment
rikAI Pro, and what the free tier is
- The free tier gives you the app with a daily allowance on a few features — photo scans, Anki cards, pronunciation checks, and a daily time budget in the Netflix, YouTube and X readers (currently 15 minutes per UTC day, shared between all three). Photo, Anki and pronunciation allowances reset by local day; cloud Ask and reader time use UTC days. The size of that allowance, and which features it covers, may change.
- rikAI Pro is an auto-renewing subscription sold through Apple's App Store. It renews at the end of each period at the price shown at purchase, charged to your Apple Account, unless you cancel at least 24 hours before the period ends. Manage or cancel it in your Apple Account settings — we cannot cancel it for you, because we never hold your payment details. Deleting the app does not cancel the subscription.
- Free trial. Where the paywall offers one, a free trial converts to a paid subscription at the end of the trial unless you cancel at least 24 hours before it ends. Apple decides whether your Apple Account is eligible for a trial; ordinarily it is one per account.
- Pro follows your Apple Account, not your phone. On a new device, or after reinstalling, use Restore purchases on the paywall.
- Refunds are Apple's, not ours. Request them through Apple. We have no ability to refund an App Store purchase.
- Prices can change for future periods. Apple provides notices and obtains consent where required by its subscription rules and applicable law.
- Cloud Ask has a separate allowance. Optional GPT-5 nano answers are currently limited to up to 10 per device per UTC day free or 200 with Pro. Network, abuse-prevention and service-wide limits also apply, so a daily allowance is a maximum, not a guarantee. Pro does not make cloud answers unlimited. On-device Ask has no cloud quota on iPhones that support the local reasoning model (at least 4 GB of memory).
- What Pro gets you is the lifting of those limits — unlimited scans, cards, checks and reader time — plus whatever else the paywall says at the time you buy it. We may add to it. If we take something away in a way that materially reduces what you paid for, you can cancel — this does not limit any refund or other remedy required by applicable law.
4 · Eligibility
Age
You must be at least 13 years old to use rikAI, and old enough to enter a binding contract where you live — or else be using it with a parent or guardian who accepts these terms for you. rikAI's built-in features carry no user-generated content, but the Netflix, YouTube and X readers open third-party content, so an adult should decide whether they are appropriate for a younger reader.
5 · Conduct
How you may use it
Use rikAI lawfully. In particular, do not use it to break the law, to infringe anyone's rights, to scrape or bulk-harvest another service, to build a competing dataset out of its output at scale, or to attack, overload or probe our servers. Do not misrepresent rikAI's output as a certified or human translation.
6 · Third parties
Readers and optional AI services
rikAI opens Netflix, YouTube and X inside the app and makes supported Japanese subtitles or posts tappable. This is a convenience layer over someone else's service, and it comes with limits you should understand before you rely on it.
- We are not them. rikAI is not affiliated with, sponsored by, endorsed by or connected to Netflix, Google LLC, YouTube, or X Corp. Their names and marks belong to them and are used only to say what the feature opens.
- Their terms apply to you there. While a reader is open you are accessing Netflix, YouTube or X, under their terms of service and privacy policies. You are responsible for complying with them, for anything done with your account, and for keeping your own credentials safe. Nothing in the readers grants you any right in their content.
- Their content is theirs, and we do not vet it. Videos, posts, images, comments and links inside the readers are third-party content. We do not create, endorse, moderate, verify or control any of it, and we are not responsible for it. Some of it may be inaccurate, offensive or otherwise objectionable; you use the readers knowing that. If you find something unlawful or harmful there, report it to the service that hosts it.
- No downloading or copying. The readers are for reading and watching in place. Do not use them to download, save, re-host or redistribute anyone's videos, subtitles, posts or images beyond what the host service and copyright law permit.
- They can break, and they can go away. The readers depend on interfaces Netflix, Google and X control and may change or withdraw at any time, without notice to us. We may need to change, limit or remove a reader. This does not limit any refund or other remedy required by applicable law.
- The natural voice. The optional VOICEVOX voice speaks as characters (四国めたん and 黒沢冴白) whose creators publish their own terms of use. Audio you generate with it is yours to use, but if you publish or distribute it, those terms apply — in particular they require you to credit the voice (for example
VOICEVOX:四国めたん). The full terms are linked from Settings → About → Licenses & credits. - The same goes for every other outside service rikAI touches: Apple's App Store and speech recognition, the Anki app, the VOICEVOX and Open JTalk projects, GitHub, SourceForge, Cloudflare and OpenAI. They are governed by their own terms, and we are not responsible for them.
6a · Optional AI
Ask with ChatGPT
Cloud Ask is optional and off by default. By choosing Allow in the disclosure shown by Settings → Model → Ask with ChatGPT, you authorize rikAI and its service providers, Cloudflare and OpenAI, to process your question, selected text and translation, recent conversation context, relevant reference facts, and assistant preferences to provide answers, as described in the privacy policy. This may include a name or nickname in your preferences and text from photos or readers. We also process a device identifier, Pro-status flag, IP address and usage counts for allowances and security.
You do not need an OpenAI account or API key and are not billed separately by OpenAI through this feature. You are responsible for having the rights and permissions needed to share the submitted content. Do not send another person’s confidential information without authority or use the feature in violation of law or the OpenAI Usage Policies. Provider policies and service availability can change.
Turn the option off to stop future cloud requests. Requests already sent remain subject to the retention described in our privacy policy. Local Ask requires an iPhone with at least 4 GB of memory and an installed reasoning model. On those phones, turning cloud Ask off or reaching the device’s daily cloud quota uses the local model. Connection and service failures show an error and do not automatically retry locally. On lower-memory phones, Ask requires your cloud permission and internet; you may decline or withdraw permission and continue using translation and dictionary tools. A failed request or fallback does not mean the request was never transmitted. Internet charges are your responsibility.
Cloud answers are AI-generated and may be inaccurate, incomplete, biased or similar to answers given to other people. Verify them before relying on them. The accuracy, warranty and liability provisions below apply to both local and cloud answers. Using OpenAI’s API does not imply that OpenAI endorses rikAI.
7 · Accuracy
rikAI is a study tool, not an authority
Translation, readings, pitch accent, grammar notes, dictionary senses, pronunciation scores and the assistant's answers are produced by machine-learning models and reference data on your phone, or by OpenAI when you enable cloud Ask. They are frequently useful and sometimes wrong — confidently wrong, in the way language models are. Treat everything rikAI says as a draft to be checked, not as a fact.
8 · Your content
What you type, say and scan
You retain your rights in the content you provide. Local chats and files are stored on your device, but content included in optional cloud Ask is processed by rikAI, Cloudflare and OpenAI. You grant us the limited permission needed to process that content and deliver the requested service, subject to the privacy policy; this does not transfer ownership to us. Keep your own backups: the cloud service is not a backup of your chats. You may use the output subject to applicable law and third-party rights; we do not promise that AI output is unique or eligible for copyright protection.
Feedback. If you send us ideas, suggestions or bug reports, we may use them freely, without owing you anything and without any obligation of confidence. How we process support correspondence and cloud Ask data is described in the privacy policy.
9 · Our content
The app, the site and the name
The app, its models, this website's writing and design, and the rikAI name and marks are ours or our licensors', protected by copyright and trademark law. These terms give you no right to use the rikAI name or marks. You may quote short passages of the site with attribution and a link.
Copyright complaints. rikAI hosts no user content, but if you believe something on this site infringes your copyright, email ryan@rikaillm.com with the work, where it appears, your contact details and a statement of good-faith belief, and we will act on it. Content inside the YouTube and X readers is hosted by them; send those notices to them.
10 · Warranty
Provided as is
Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you. Nothing here limits any non-waivable statutory right you have as a consumer.
11 · Liability
Limitation of liability
This limit applies in particular, and without limiting the generality of the above, to: any error, omission or invention in a translation, reading, pitch accent, grammar note or assistant answer, and anything you do or fail to do in reliance on one; any third-party content, service or account reached through the Netflix, YouTube or X readers or any other link; any interruption, change, degradation or discontinuation of the Service or a reader; any loss of chats, cards, models or settings on your device; and any act or omission of Apple, Google, X, Netflix, Cloudflare, OpenAI or any other third party.
These exclusions and limits are an essential part of the bargain between us and apply even if a limited remedy fails of its essential purpose. Nothing in these terms excludes or limits liability that cannot be excluded or limited by law — including, where the law so provides, liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for wilful misconduct or gross negligence. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages; where that is so, the exclusions above apply only as far as the law allows, and our liability is limited to the smallest amount permitted.
12 · Indemnity
If your use of rikAI causes a claim
You will defend, indemnify and hold harmless rikAI LLC and the people listed in section 11 from any claim, loss, liability, damage, fine or expense (including reasonable legal fees) arising out of your use of the Service, your breach of these terms or of any law, your violation of anyone's rights, or your use of a third-party service through rikAI. We may take over the defence of any such claim at our own expense, and you will cooperate with it.
13 · Disputes
Arbitration, and no class actions
- Talk to us first. Before starting anything formal, email ryan@rikaillm.com with a description of the problem and what you want. Most things end here. If it isn't resolved within 30 days, either of us may proceed.
- Arbitration. Any dispute arising out of or relating to the Service or these terms that is not resolved informally will be settled by binding arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, before one arbitrator, in the English language. The arbitration may be conducted by written submission, by telephone or video, or in person in the county where you live, at your election. The arbitrator's award may be entered as a judgment in any court with jurisdiction. The Federal Arbitration Act governs this section.
- Fees. The AAA's Consumer Arbitration Rules cap what you pay. For a claim of US$10,000 or less we will pay the AAA's filing, administrative and arbitrator fees, unless the arbitrator finds the claim frivolous or brought for an improper purpose. Each side pays its own lawyers unless the law or the arbitrator says otherwise.
- Who decides what. The arbitrator, not a court, decides whether a dispute falls within this section, except that a court decides the enforceability of the class-action waiver below. The arbitration and its outcome are confidential except as needed to enforce the award.
- What is not arbitrated. Either of us may bring an individual claim in small-claims court if it qualifies, and either of us may seek injunctive relief in court to stop infringement or misuse of intellectual property. For any claim that does go to court, you and rikAI LLC each waive the right to a jury trial to the fullest extent the law allows.
- Individually, only. You and rikAI LLC each agree to bring claims only in an individual capacity, and not as a plaintiff or class member in any class, collective, consolidated or representative proceeding. The arbitrator may not consolidate claims or preside over any form of representative proceeding. If this paragraph is found unenforceable as to a particular claim or request for relief, that claim or request is severed and must be brought in court under section 14, and the rest of this section 13 still applies to everything else.
- Opting out. You may reject this arbitration agreement by emailing ryan@rikaillm.com with your name and the words "arbitration opt-out" within 30 days of first accepting these terms (or, if we later change this section materially, within 30 days of the change taking effect). Opting out costs you nothing else and does not affect any other part of these terms. This section survives the end of your relationship with rikAI.
14 · Law
Governing law and venue
These terms and any dispute under them are governed by the laws of the Commonwealth of Pennsylvania, United States, without regard to its conflict-of-laws rules and excluding the United Nations Convention on Contracts for the International Sale of Goods. For any dispute not subject to arbitration under section 13, you and we consent to the exclusive jurisdiction and venue of the state and federal courts located in Pennsylvania, and each waive any objection to that venue. Any claim must be brought within one year after it arises, or it is permanently barred, except where a longer period is required by law.
If you live outside the United States and are using rikAI as a consumer, nothing in sections 10 to 14 takes away protections you are entitled to under the mandatory law of your own country, including any right to bring a claim in your own courts. Where a provision here conflicts with that law, that law wins for you and the provision applies as far as it can. The English text of these terms controls over any translation.
You use the Service on your own initiative and are responsible for complying with your own local law. You confirm you are not located in a country subject to a U.S. Government embargo or designated as terrorist-supporting, and are not on any U.S. Government list of prohibited or restricted parties.
15 · Apple
Terms Apple requires
Because rikAI is distributed through the App Store, the following applies and, where it conflicts with the rest of these terms, it governs:
- This agreement is between you and rikAI LLC only, not with Apple. Apple is not responsible for rikAI or its content.
- Apple has no obligation to provide any maintenance or support for rikAI. Support is ours, at rikaillm.com/support.
- If rikAI fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price of the app to you (if any). To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to rikAI, and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are ours.
- rikAI LLC, not Apple, is responsible for addressing any claim by you or a third party relating to rikAI or your use of it, including product liability claims, any claim that rikAI fails to conform to a legal or regulatory requirement, and claims under consumer protection or similar law.
- rikAI LLC, not Apple, is responsible for the investigation, defence, settlement and discharge of any third-party claim that rikAI infringes that party's intellectual property rights.
- Apple and its subsidiaries are third-party beneficiaries of these terms and, upon your acceptance, have the right to enforce them against you.
16 · Changes
Changes, suspension and the rest
- To the Service. We may change, suspend or discontinue any part of the Service, including any feature or reader, at any time. We will not take rikAI Pro's paid features away without cause during a period you have paid for; if we do, cancel and Apple's refund policy applies.
- To these terms. The current version always lives at this address with its effective date at the top. If we make a material change we will say so in the app or on the site. Continuing to use the Service after a change takes effect means you accept it; if you don't, stop using the Service and cancel any subscription.
- Pre-release builds. A beta or pre-release version of rikAI — through TestFlight or otherwise — is for testing, may be unstable or incomplete, may stop working at any time, and is covered by these terms and Apple's TestFlight terms. Don't put anything you can't lose in one.
- Things outside our control. We are not liable for any failure or delay caused by something beyond our reasonable control — an outage at Apple, Cloudflare, OpenAI, Google, Netflix or X, a change to their interfaces, a network failure, a natural disaster, a government act, or the like.
- Termination. You may stop at any time by deleting the app. We may suspend or terminate your licence if you materially breach these terms. Sections 2 (the restrictions), 6 through 15, and this section survive termination.
- Severability and waiver. If any provision is held unenforceable, it is limited or severed to the minimum extent necessary and the rest stays in force. Our not enforcing something is not a waiver of it.
- Assignment. You may not assign these terms. We may assign them to a successor in connection with a merger, acquisition or sale of assets.
- Entire agreement. These terms and the privacy policy are the whole agreement between you and rikAI LLC about the Service, and replace anything said before it. Nothing here creates a partnership, agency or employment relationship.
- Reading these terms. "Including" means "including without limitation". Headings are for finding your way, not for interpretation. No rule construing a document against its drafter applies.
- California residents. Under California Civil Code §1789.3, you may reach the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs in writing at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by telephone at (800) 952-5210.
