Terms of Use
The rules for reading RAKKAN, holding an account, paying for a plan and using the API. The short version: RAKKAN estimates, it does not promise, and you decide what to do with its estimates.
In effect from 29 September 2026 · Privacy Notice
1. Agreement
These Terms of Use (the Terms) are a binding agreement between you and Calderaro (RAKKAN, we, us) covering the website, its accounts, its paid plans, its API, its emails and webhooks, and everything else we offer under the RAKKAN name (the Service).
By using the Service, creating an account, or ticking the box at sign-up, you confirm that you have read and accept these Terms and the Privacy Notice. If you do not accept them, do not use the Service. If you use it on behalf of an organisation, you confirm you are authorised to bind it, and “you” includes that organisation.
2. Who may use it
- You must be at least 16 years old, or older where your country requires it, to hold an account.
- You must be of legal age to enter a contract where you live to buy a paid plan.
- You may not use the Service if the law where you are forbids it, or if we have previously closed your account.
3. What RAKKAN is, and is not
RAKKAN collects what third parties publicly say about manga, manhwa, manhua and anime, records who said it and when, and applies automated rules, statistical models and machine-learning systems to estimate how likely each statement is to be true and when events may happen.
Everything on the Service is information for general interest only. Claims, rumors, states, confidence levels, grades, forecasts, intervals, probabilities and calibration figures are automated estimates. They can be incomplete, late, out of date, misattributed or simply wrong. Sources we read make mistakes, and so do our extraction, matching and models.
Nothing on the Service is professional, financial, investment, legal, licensing, purchasing or business advice, and nothing on it is a statement of fact by us or by any publisher, studio or rights holder. You are solely responsible for any decision you make using it, and you should verify anything that matters to you with the official source before acting on it.
4. Your account
- Give accurate information at sign-up and keep your email address current.
- Keep your password and API keys secret. You are responsible for everything done with your account or keys until you tell us they were compromised.
- One account per person. Accounts, plans and keys may not be shared, sold or transferred.
- You can delete your account at any time from the account page. Deletion is permanent and cannot be undone (see the Privacy Notice).
5. Paid plans and billing
Paid plans are sold through Polar (polar.sh), which acts as merchant of record: it takes the payment, charges any applicable taxes and issues the invoice, under its own terms. We never see or store your card details.
- Subscriptions renew automatically at the end of each billing period until you cancel.
- You can cancel at any time from the account page. Cancellation stops the next renewal; your plan stays active until the end of the period you already paid for, then returns to Free.
- Fees are non-refundable, including for partly used periods, unused features or downtime, except where a refund is required by law that cannot be excluded (for example, a statutory right of withdrawal).
- We may change prices and what each plan includes. A price change applies from your next renewal after we tell you about it, and you may cancel before it takes effect.
- Terminal and other contracted plans are governed by their own order form where one exists, which prevails.
6. Licence to use the Service and the API
While you comply with these Terms, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable and revocable licence to view the Service and, on plans that include it, to call the API within your plan’s limits, for your own internal use.
Unless we agree otherwise in writing, you may not:
- copy, scrape, crawl or bulk-download the Service, other than through the API within your limits;
- resell, redistribute, republish, sublicense or make available the Service or its data, or use it to build, train or improve a competing product, dataset or machine-learning model;
- get around rate limits, plan gates, CAPTCHAs or any other access control, or create accounts automatically;
- reverse engineer, decompile or attempt to obtain the source code, models or non-public data of the Service;
- probe, scan or test the Service’s security, or interfere with its operation or other users.
Where we allow you to quote small parts of the Service publicly, you must credit RAKKAN and link to the page you quote.
7. Acceptable use
You may not use the Service to:
- break any law, or infringe anyone’s intellectual property, privacy or other rights;
- find, share or promote unlicensed copies of any work;
- submit false, misleading, abusive or automated reports, takedown notices or requests;
- send spam, malware or anything harmful through webhooks or any other feature;
- harass anyone, or impersonate any person or organisation.
8. Third-party content and services
The Service describes and links to content published by third parties: news sites, publishers, social networks, databases such as AniList, and others. We do not control, endorse or take responsibility for that content, for its accuracy, or for the sites it lives on. Following a link is at your own risk.
Titles, names, logos, cover images and other marks belong to their owners. Their appearance on the Service is for identification only and implies no affiliation, sponsorship or endorsement.
The Service relies on third-party providers (hosting, databases, email, payment, CAPTCHA). We are not responsible for their acts, failures or terms.
9. What you send us
When you send us a report, a correction, feedback, a request or any other submission, you grant us a worldwide, perpetual, irrevocable, royalty-free licence to use, copy, modify and incorporate it into the Service, without obligation to you. You confirm you have the right to grant it. We may use feedback freely and owe nothing for it.
10. Our rights
The Service, including its software, design, text we write, compiled datasets, grades, forecasts, models and the RAKKAN name and seal, belongs to us or our licensors and is protected by law. Except for the limited licence in section 6, these Terms give you no right in any of it.
11. Copyright and takedown notices
We never reproduce works. If you believe something on the Service infringes your rights, file a notice on the takedown page. Knowingly false notices may make the sender liable for damages. We may close the accounts of repeat infringers.
12. No warranties
To the fullest extent permitted by law, the Service and everything on it are provided “as is” and “as available”, with all faults and without warranties of any kind, express, implied or statutory, including warranties of accuracy, completeness, timeliness, reliability, availability, merchantability, fitness for a particular purpose, title and non-infringement. We do not warrant that the Service will be uninterrupted, secure or error-free, that defects will be corrected, that any claim or forecast will be correct, or that any data will be preserved. You use the Service at your own risk.
13. Limitation of liability
To the fullest extent permitted by law, we and our operators, contractors, suppliers and licensors will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, business, opportunity, goodwill, data or anticipated savings, or for the cost of substitute services, arising out of or related to the Service or these Terms, however caused and on any theory of liability, even if we were told they were possible.
To the fullest extent permitted by law, our total liability for all claims arising out of or related to the Service or these Terms will not exceed the greater of (a) the amount you paid us for the Service in the twelve months before the event giving rise to the claim, and (b) fifty US dollars (US$50).
In particular, we are not liable for decisions you make, or losses you suffer, because a claim, grade or forecast on the Service was wrong, late or missing; for the acts or content of any third party or source; or for interruptions, loss of data or security incidents beyond our reasonable control.
14. Your responsibility to us
To the extent permitted by law, you will defend, indemnify and hold harmless us and our operators, contractors and suppliers from any claim, demand, loss, damage, cost or expense (including reasonable legal fees) brought by a third party or arising from your use of the Service, your submissions, your breach of these Terms, or your violation of any law or of anyone’s rights.
15. Suspension, termination and changes to the Service
We may suspend or close your account, revoke API keys, or refuse the Service to anyone, at any time, with or without notice, if we reasonably believe these Terms were broken, to protect the Service or others, or where the law requires it. Where we close a paid account without a breach on your part, we refund the unused part of the current period.
We may change, suspend or discontinue any part of the Service, including sources, features, models and plans, at any time. Sections that by their nature should survive termination (including sections 3, 6, 9, 10, 12 to 14, 17 and 18) survive it.
16. Changes to these Terms
We may update these Terms. We will post the new version here with its date and, for material changes affecting account holders, tell you by email or on the site before they take effect. Continuing to use the Service after that means you accept them; if you do not, stop using the Service and delete your account.
17. Governing law, disputes and your statutory rights
These Terms are governed by the laws of the Federative Republic of Brazil, without regard to conflict-of-law rules. Disputes will be heard exclusively by the courts of the operator's domicile, except where the law gives you the right to bring proceedings where you live.
Nothing in these Terms excludes or limits any right or liability that cannot be excluded or limited under the law that applies to you, including consumer protection law such as Brazil’s Consumer Defence Code (Law 8.078/1990) and the mandatory consumer laws of the European Union and United Kingdom, or liability for fraud, wilful misconduct or gross negligence. Where such a law applies, the exclusions and limits above apply only as far as it allows.
18. General
- These Terms and the Privacy Notice are the whole agreement between you and us about the Service.
- If any part is found unenforceable, it is enforced as far as possible and the rest remains in effect.
- Not enforcing a right is not a waiver of it.
- You may not assign these Terms; we may assign them to a successor to the Service.
- We are not responsible for failures caused by events beyond our reasonable control, including outages of third-party providers, network failures, natural events and acts of government.
- If these Terms are translated, the English version prevails.
