Terms of Service

You must be at least 18 years of age and capable of entering into a legally binding contract to use the Service. By using the Service, you represent and warrant that you meet these requirements.

• You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account.
• You must notify us immediately if you suspect unauthorized use of your account.
• We may suspend or terminate your account at any time, with or without cause, with or without notice.
• Creating an account, signing in, or otherwise continuing to use the Service after the Effective Date of these Terms constitutes your acceptance of these Terms. We may, at our discretion, require explicit re-acceptance on material changes.

You agree not to:

• Use the Service for any unlawful purpose or in violation of applicable law;
• Transmit malware, spam, phishing, or other harmful content;
• Attempt to disrupt, degrade, probe, or gain unauthorized access to the Service or its related systems;
• Scrape, crawl, or use bots, robots, spiders, or other automated means to access or extract data from the Service (other than via official APIs subject to their own terms);
• Bypass or attempt to bypass tier limits, rate limits, paywalls, or other access controls;
• Reverse engineer, decompile, or attempt to extract source code or proprietary algorithms from the Service, including the AI models that power it;
• Use outputs of the Service to develop, train, fine-tune, or evaluate any artificial intelligence or machine learning model that competes with the Service;
• Resell, sublicense, lease, or otherwise commercially redistribute the Service or access to it without our prior written consent;
• Harass, threaten, abuse, or intentionally direct unwanted contact at other users in shared workspaces;
• Submit content that infringes any third party's intellectual property, privacy, or other rights.

We reserve the right to investigate violations and take appropriate action, including suspension or termination of your account.

• Ownership: You retain ownership of content, data, or materials you submit through the Service ("User Content").
• Limited License to Us: By submitting User Content, you grant us a limited, worldwide, non-exclusive, royalty-free license to use, process, store, transmit, and display User Content solely for the purpose of operating, providing, securing, and improving the Service for you. This license terminates with respect to User Content when you delete it or close your account, except (i) for content you have publicly shared and that remains in the platform, (ii) for content retained in backups for a limited period, and (iii) where retention is required by law.
• No Training of Third-Party AI Models: We do not use your User Content to train third-party generative AI models, and we do not authorize the third-party large-language-model providers we use to do so. Our contractual arrangements with these providers prohibit them from using User Content sent through Chask to train their general-purpose models.
• Internal Model Improvement: We may use aggregated, de-identified usage signals and explicit user feedback (such as thumbs-up/down ratings and submitted bug reports) to evaluate, improve, and select internal prompt templates and ranking heuristics used by the Service. These signals do not include the substantive content of your goals or chat messages in a form that identifies you.
• Third-Party Processing: User Content may be transmitted to third-party subprocessors to provide the Service. See our Subprocessors page for the current list.
• Your Responsibility: You represent that you have the rights and permissions necessary to submit User Content and to grant the rights described above.

By using Chask's AI-powered features, you acknowledge and agree to the following:

• AI Provider Disclosure: Chask uses OpenAI as its primary large-language-model provider. Content you submit to AI-powered features (goal statements, chat messages, planning prompts, and similar inputs) is processed by OpenAI subject to OpenAI's own data policies. We maintain contractual safeguards described in Section 4 above and list current subprocessors at /subprocessors.
• Goal Breakdowns & Task Suggestions: AI-generated breakdowns, milestones, and task suggestions are provided for general goal-planning guidance only and may not be accurate, complete, current, or suitable for your specific situation.
• No Professional Advice: Chask does not provide medical, mental-health, legal, financial, tax, investment, or other professional advice. AI-generated suggestions are not a substitute for advice from a qualified professional. Always consult a qualified professional for decisions in these areas.
• User Responsibility: You are solely responsible for reviewing, modifying, and acting upon any AI-generated content. We make no warranty that AI suggestions will be accurate, complete, fit for purpose, or free of errors.
• Interaction with AI: You acknowledge that AI features may produce factually incorrect, biased, or otherwise inappropriate output, and that such output should be treated as a starting point for your own judgment.
• Continuous Improvement: AI features may change, improve, or be modified without notice as we refine our algorithms and prompts.

Your use of the Service is also subject to our Privacy Policy, which explains how we collect, use, and share information about you.

We may suspend or terminate your account or access to the Service at any time, with or without cause, with or without notice. Upon termination, your right to use the Service will cease immediately.

Upon termination of your account (whether by you or by us), you will have 30 days from the date of termination to request an export of your User Content by emailing privacy@chask.ai. We will provide your User Content in a commonly used, machine-readable format. After this 30-day window, your User Content may be permanently deleted from our active systems, except where retention is required by applicable law (in which case the retention is limited to what is legally required, and the data is otherwise inaccessible to ongoing operations).

Certain sections of these Terms will survive termination, including but not limited to: Content and Data, Disclaimers, Limitation of Liability, Indemnification, and Governing Law.

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

We do not warrant that the Service will be error-free, uninterrupted, secure, or free of harmful components.

To the maximum extent permitted by law:

• We shall not be liable for any indirect, incidental, consequential, special, or punitive damages, including without limitation damages for loss of profits, data, use, goodwill, or other intangible losses.
• Our total liability for any claim related to the Service will not exceed the greater of (a) the amount you paid us in the 12 months preceding the claim, or (b) USD $100.

You agree to indemnify, defend, and hold harmless Chask, Inc., its affiliates, officers, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to:

• Your use of the Service;
• Your violation of these Terms;
• Your violation of any rights of another party, including intellectual property rights.

We may revise these Terms at any time by posting an updated version on the Service. Your continued use of the Service after changes become effective constitutes your acceptance of the revised Terms.

For material changes to these Terms — including changes affecting fees, dispute resolution, limitations on liability, or the categories of data we process — we will provide at least 30 days' notice via email to the address on your account before the changes take effect. Non-material changes (such as clarifications, formatting fixes, or contact-information updates) may take effect when posted.

• Entire Agreement: These Terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding the Service.
• Severability: If any provision is found unenforceable, the remaining provisions remain in effect.
• No Waiver: Our failure to enforce any right or provision shall not be deemed a waiver of such right or provision.
• Assignment: You may not assign or transfer your rights under these Terms without our prior consent.

If you have any questions about these Terms, please contact us at:

During the beta, we actively encourage you to submit feedback, suggestions, ideas, feature requests, bug reports, and other input ("Feedback") through in-app channels, email, surveys, community discussions, or any other means.

By submitting Feedback, you grant Chask a perpetual, irrevocable, worldwide, royalty-free, fully sublicensable license to use, reproduce, modify, create derivative works of, publicly display, distribute, and commercially exploit your Feedback for any purpose, including incorporating it into the Service or our other products.

You agree that:

• Chask has no obligation to use, credit, compensate, or notify you regarding any Feedback;
• Feedback is provided without any expectation of confidentiality;
• You will not submit Feedback that is confidential to a third party, that infringes any patent or copyright, or that you do not have the right to submit;
• Submitting Feedback does not create any obligation of Chask to maintain, support, or extend any feature you discuss in your Feedback.

Chask respects intellectual property rights and complies with the procedures of the Digital Millennium Copyright Act (DMCA), 17 U.S.C. § 512. If you believe that content hosted on the Service infringes your copyright, send a written notice to our designated agent including all of the elements required by 17 U.S.C. § 512(c)(3):

• A physical or electronic signature of the person authorized to act on behalf of the copyright owner;
• Identification of the copyrighted work claimed to be infringed;
• Identification of the allegedly infringing material and information reasonably sufficient to permit us to locate it on the Service;
• Your contact information (address, telephone number, email);
• A statement that you have a good-faith belief that the disputed use is not authorized by the copyright owner, its agent, or the law;
• A statement, made under penalty of perjury, that the information in the notice is accurate, and that you are the copyright owner or authorized to act on the owner's behalf.

Send DMCA notices to: dmca@chask.ai.

We have a policy of terminating accounts of users who are determined to be repeat infringers.

Counter-Notice: If you believe content you submitted to the Service was removed in response to a mistaken or misidentified DMCA notice, you may submit a counter-notice to dmca@chask.ai containing the elements required by 17 U.S.C. § 512(g)(3). Full takedown and counter-notice procedures are described at /dmca.

To operate the Service, Chask relies on a number of third-party service providers ("Subprocessors"), each of which processes data described in our Privacy Policy. Current Subprocessors include:

• OpenAI — large-language-model inference for AI-powered features (goal breakdowns, chat, planning suggestions);
• Supabase — database, authentication, real-time, and file storage;
• Sentry — error monitoring and performance tracing;
• PostHog — product analytics (opt-in only, subject to your consent preferences);
• Google (Calendar OAuth) — Google Calendar integration (only when you authorize a connection via OAuth);
• Stripe — payment processing for paid subscriptions;
• Resend — transactional email delivery (verification, password resets, account notifications);
• Redis-compatible cache — short-lived caching of AI responses to reduce LLM calls.

A current list of Subprocessors, including the data they process and their purposes, is maintained at /subprocessors. Each Subprocessor is contractually obligated to maintain the confidentiality and security of your data and to use it only to provide services to Chask.

We may engage new Subprocessors or change existing ones from time to time. Material changes will be disclosed on the Subprocessors page and, for changes that materially affect the categories of data processed, via notice under Section 13.
