1. Acceptance of these Terms

These Terms of Service ("Terms") form a binding agreement between you and Thinkr, a product operated from the Republic of Indonesia ("Thinkr", "we", "us", or "our"), and govern your access to and use of the Thinkr website at https://usethinkr.com, the Thinkr web application hosted on its application subdomain, and all related features, integrations, and services (together, the "Service").

By creating an account, clicking to accept these Terms, or otherwise accessing or using the Service, you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy and Refund Policy, which are incorporated here by reference. If you do not agree, you must not access or use the Service.

If you are using the Service on behalf of a company, team, or other organization, you represent that you have authority to bind that organization to these Terms, and "you" refers to both you individually and that organization.

"User Content" means any data, documents, files, sources, prompts, text, or other material you upload to, submit to, or generate within the Service, including sources you add to the Notebook.
"AI Output" means any content the Service generates using artificial intelligence in response to your inputs, including generated PRDs and specifications, critiques, proposals, prototypes, and notebook responses.
"Notebook" (also referred to as the "Brain") means the research workspace that ingests and stores your uploaded sources to power retrieval and generation.

3. Eligibility and age

You must be at least 18 years old, or the age of legal majority in your jurisdiction, to use the Service. By using the Service, you represent and warrant that you meet this requirement and that you are not barred from receiving the Service under the laws of Indonesia or any other applicable jurisdiction.

The Service is a professional productivity tool intended for business use by product managers and product teams. It is not directed to children, and we do not knowingly collect personal data from children. If you believe a minor has provided us personal data, please contact us at support@usethinkr.com.

4. Description of the Service

Thinkr is an AI workspace for product managers and product teams. Depending on your plan, the Service may include:

PRD and spec generation — AI-assisted drafting of product requirement documents and specifications;
Critique — AI review and feedback on product specs and related documents;
Notebook / Brain — a research workspace that ingests user-uploaded sources and documents to support retrieval and grounded generation;
Proposal generation and prototype generation; and
Third-party integrations that connect the Service to other tools you use.

AI-generated content. Several features rely on third-party LLM providers to generate output. We send relevant portions of your inputs and User Content to these providers to produce AI Output. AI Output is generated automatically, may be inaccurate, incomplete, biased, or out of date, and is provided strictly on an "as is" basis. See Section 10 (User Content and uploaded sources), Section 11 (AI Output and disclaimer), and Section 13 (Third-party services).

We may add, change, suspend, or remove features of the Service at any time. We may also impose or change usage limits (for example, on generations, storage, or uploads) by plan tier.

5. Accounts and security

To use most features you must register an Account and provide accurate, current, and complete information. You are responsible for:

maintaining the confidentiality of your login credentials;
all activity that occurs under your Account; and
promptly notifying us at support@usethinkr.com of any unauthorized use or suspected security breach.

You must not share your credentials, allow others to use your Account in violation of plan limits, or create an Account through automated means. We are not liable for any loss or damage arising from your failure to safeguard your credentials. We may refuse, suspend, or cancel an Account, or reclaim a username, if we reasonably believe these Terms have been violated.

6. Subscription plans and the Free tier

Thinkr is offered across four tiers: Free, Pro, Plus, and Max. Each tier provides a different set of features and usage limits, described on our pricing page. We may change the features, limits, or pricing of any tier; for paid tiers, material price changes will take effect from your next renewal and we will give you reasonable advance notice.

Free tier. The Free tier is provided at no charge and may have reduced features and limits. Because no payment is charged for the Free tier, no refunds apply to it. We may modify, limit, or discontinue the Free tier at any time.

Paid tiers. Pro, Plus, and Max are paid Subscriptions billed on a monthly or annual basis, as you select at checkout. Each paid tier is a recurring Subscription that automatically renews as described in Section 7.

7. Billing, auto-renewal, and Lemon Squeezy as Merchant of Record

Merchant of Record. All payments for paid Subscriptions are processed by Lemon Squeezy, which acts as the Merchant of Record (reseller / seller of record) for your purchase. This means:

Your contract for payment is with Lemon Squeezy as the seller of record, while the software service is provided to you by Thinkr under these Terms.
Lemon Squeezy handles payment processing, billing, invoicing, and the calculation, collection, and remittance of any applicable sales tax, VAT, or GST on your purchase.
Your purchase is also subject to Lemon Squeezy's own terms and privacy policy, in addition to these Terms.

Pricing and taxes. Prices are stated on our pricing page and at checkout. Depending on your location, taxes may be added by Lemon Squeezy at checkout and shown before you confirm your purchase.

Auto-renewal. Paid Subscriptions renew automatically at the end of each billing term (monthly or annual) at the then-current price for your plan, using the payment method on file with Lemon Squeezy, until you cancel. By purchasing a Subscription, you authorize Lemon Squeezy to charge your payment method on each renewal date until you cancel.

Failed payments. If a renewal payment fails, we may suspend or downgrade your access until payment is resolved.

Cancellation. You may cancel your Subscription at any time, effective at the end of the current paid billing term. After cancellation you retain access to your paid features until the end of the period you have already paid for, and you will not be charged again. Cancelling does not by itself entitle you to a refund of amounts already paid — see Section 8 and the Refund Policy.

8. Refunds

We offer a 14-day money-back guarantee. You may request a full refund of a paid Subscription within 14 days of the initial purchase or first charge of a billing term, no questions asked.

After that 14-day window, payments are non-refundable. You may still cancel at any time to stop future renewals, and your access will continue until the end of the paid period.

Because Lemon Squeezy is the Merchant of Record, refunds are issued through Lemon Squeezy. You may initiate a refund request with us at support@usethinkr.com and we will arrange for it to be processed via Lemon Squeezy, or you may contact Lemon Squeezy directly. The Free tier involves no charges and is therefore not eligible for refunds.

Full details, including how to request a refund and any exceptions, are set out in our Refund Policy, which forms part of these Terms.

9. Acceptable use and prohibited conduct

You agree to use the Service only for lawful purposes and in compliance with these Terms. You must not:

violate any applicable law or regulation, including Indonesian law and the laws of your jurisdiction;
upload, generate, or distribute content that is unlawful, infringing, defamatory, harassing, or that violates the privacy or intellectual property rights of others;
upload User Content you do not have the right to upload, or that you are contractually or legally barred from sharing with third-party processors;
attempt to reverse engineer, decompile, scrape, or extract the source code or models underlying the Service, except to the extent this restriction is prohibited by law;
circumvent usage limits, rate limits, access controls, or plan entitlements;
use the Service to build or train a competing product, or to resell the Service without our written permission;
interfere with, disrupt, or place undue load on the Service or its infrastructure, or introduce malware or other harmful code;
use the AI features to generate content that is harmful, deceptive, or otherwise violates the acceptable-use policies of our LLM sub-processors; or
use the Service to make automated decisions about individuals that produce legal or similarly significant effects without appropriate human review.

We may investigate suspected violations and may suspend or terminate access in accordance with Section 18.

10. User Content and uploaded sources

Your ownership. As between you and Thinkr, you retain all ownership of your User Content, including the sources and documents you upload to the Notebook and the inputs you provide. We do not claim ownership of your User Content.

License you grant to us. To operate the Service, you grant Thinkr a worldwide, non-exclusive, royalty-free license to host, store, copy, transmit, process, display, and create derived data from your User Content solely for the purposes of: (a) providing, maintaining, and securing the Service to you; (b) generating AI Output you request, which includes transmitting relevant inputs to our LLM sub-processors; and (c) complying with law. This license lasts only as long as needed for those purposes and ends when you delete the relevant User Content or close your Account, subject to routine backups and legal retention.

No training on your content without permission. We do not use your User Content to train our own or third parties' foundation models except as permitted by law and our Privacy Policy. We engage LLM sub-processors under terms that, to our knowledge, do not use submitted content to train their general models for non-enterprise API usage; however, your use of the AI features is also subject to those providers' terms.

Your responsibilities. You represent and warrant that you have all rights, consents, and permissions necessary to upload your User Content and to allow us and our sub-processors to process it as described. You are responsible for the accuracy and legality of your User Content, and for not uploading sensitive personal data, regulated data, or confidential third-party information that you are not permitted to share.

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

11. AI Output and disclaimer of accuracy

AI Output is generated by automated systems and may be inaccurate, incomplete, misleading, biased, or out of date. AI Output is provided "as is".

You must review. You are solely responsible for reviewing, validating, and editing any AI Output before relying on it or sharing it. Do not treat AI Output as a substitute for your own professional judgment.
Not professional advice. AI Output does not constitute legal, financial, medical, engineering, or other professional advice. You should obtain advice from a qualified professional where appropriate.
No guarantee of uniqueness. Given how generative models work, AI Output provided to you may be similar to output provided to other users. To the extent permitted by law and by our LLM sub-processors' terms, we do not assert ownership of AI Output as against you, and as between you and Thinkr you may use AI Output you generate subject to these Terms; however, we make no representation that AI Output is free of third-party rights, and you are responsible for ensuring your use of it is lawful.

Thinkr is not liable for any decision you make or action you take based on AI Output. See Sections 15 and 16.

12. Intellectual property in the Thinkr platform

The Service, including its software, models and prompts we develop, user interface, design, text, graphics, logos, trademarks, and all related intellectual property, is owned by Thinkr or its licensors and is protected by Indonesian and international intellectual property laws.

Subject to your compliance with these Terms and payment of applicable fees, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Service for your internal business purposes during your subscription term. All rights not expressly granted are reserved. You may not copy, modify, distribute, sell, lease, or create derivative works of the Service, and you may not remove or alter any proprietary notices.

"Thinkr" and the Thinkr logo are trademarks of Thinkr. You may not use them without our prior written consent.

13. Third-party services and integrations

The Service relies on and may interoperate with third parties, including:

LLM providers (currently Google, via the Google Gemini API) that generate AI Output from your inputs;
Lemon Squeezy, our Merchant of Record for payments;
cloud hosting and infrastructure providers; and
integrations you choose to connect to the Service.

Your use of any third-party service is governed by that third party's own terms and privacy policies, and we are not responsible for third-party products, services, or content. When you enable an integration, you authorize us to exchange data with that third party as needed to provide the integration. You are responsible for your use of integrations and for any data shared through them. We may suspend or remove any integration at any time. A current list of our key sub-processors is described in our Privacy Policy.

14. Privacy and data protection

Our handling of personal data is described in our Privacy Policy, which forms part of these Terms. In summary:

We process personal data in accordance with Indonesia's Undang-Undang No. 27 Tahun 2022 tentang Pelindungan Data Pribadi (UU PDP).
For users in the EU/EEA and the UK, we also act consistently with the GDPR / UK GDPR, including providing a lawful basis for processing and honoring data-subject rights.
For all other users, we apply the protections described in our Privacy Policy on an international basis.
We use Google Analytics 4 on our marketing site, and we engage LLM, hosting, and payment sub-processors to deliver the Service.

For privacy or data-protection requests, contact privacy@usethinkr.com. For all other matters, contact support@usethinkr.com.

15. Disclaimers and "as is"

To the maximum extent permitted by applicable law, the Service and all AI Output are provided "as is" and "as available," without warranties of any kind, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, or that the Service will be uninterrupted, secure, or error-free.

We do not warrant that AI Output will be accurate, reliable, complete, or suitable for your purposes. You use the Service and rely on AI Output at your own risk. Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you; in that case, our warranties are limited to the minimum extent required by law.

16. Limitation of liability

To the maximum extent permitted by applicable law:

Thinkr and its affiliates, directors, employees, and suppliers will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or business opportunities, arising out of or relating to the Service or AI Output, even if advised of the possibility of such damages.
Thinkr's total aggregate liability for all claims arising out of or relating to these Terms or the Service will not exceed the greater of (a) the total amounts you paid to Lemon Squeezy for the Service in the twelve (12) months preceding the event giving rise to the claim, or (b) USD 100 (or its equivalent).

These limitations apply regardless of the legal theory and form the basis of the bargain between you and us. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable mandatory law.

17. Indemnification

You agree to indemnify, defend, and hold harmless Thinkr and its affiliates, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to: (a) your User Content; (b) your use of the Service or AI Output; (c) your violation of these Terms or any applicable law; or (d) your violation of the rights of any third party. We will notify you of any such claim and may, at our option, participate in or assume control of its defense.

18. Suspension and termination

By you. You may stop using the Service and close your Account at any time. Cancellation of paid Subscriptions is governed by Section 7 and refunds by Section 8.

By us. We may suspend or terminate your access, in whole or in part, with or without notice, if: (a) you breach these Terms or our Acceptable Use rules; (b) your use poses a security, legal, or operational risk to us or others; (c) required by law; or (d) for prolonged non-payment.

Effect of termination. On termination, your right to use the Service ends. We may delete your Account and User Content after a reasonable period, subject to backups and legal retention obligations described in our Privacy Policy. You are responsible for exporting any User Content you wish to keep before termination. Sections that by their nature should survive termination (including Sections 10–17 and 19–21) will survive.

19. Changes to the Service and to these Terms

We may modify, suspend, or discontinue any part of the Service at any time. We may also update these Terms from time to time. When we make material changes, we will update the "Effective date" below and take reasonable steps to notify you, such as by email or an in-app notice.

Changes take effect when posted unless we state otherwise. Your continued use of the Service after changes take effect constitutes acceptance of the revised Terms. If you do not agree to the changes, you must stop using the Service and may cancel your Subscription.

20. Governing law and dispute resolution

These Terms and any dispute arising out of or relating to them or the Service are governed by the laws of the Republic of Indonesia, without regard to conflict-of-laws principles.

Before initiating any formal proceeding, you agree to first contact us at support@usethinkr.com and attempt in good faith to resolve the dispute informally for at least thirty (30) days. If the dispute cannot be resolved informally, it will be submitted to the competent courts of the Republic of Indonesia, unless a different forum is required by applicable mandatory law.

Nothing in this Section limits any mandatory consumer-protection rights you may have under the laws of your country of residence.

21. General

Entire agreement. These Terms, together with the Privacy Policy and Refund Policy, are the entire agreement between you and Thinkr regarding the Service.
Severability. If any provision is held unenforceable, the remaining provisions remain in effect.
No waiver. Our failure to enforce any provision is not a waiver of it.
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.
