These Terms explain how the Google Calendar Event Checker Chrome extension (the "Service") offered by CalCheckr, the operator of the calcheckr.com domain ("CalCheckr," "we," or "us") is provided at this time. By installing or using the Chrome extension you agree to follow these guidelines. If you do not agree, please do not use the Service.
CalCheckr is a product name and not a separate legal entity; the Service is operated by the individual who owns the calcheckr.com domain.
You represent that you are at least 18 (or the age of majority in your jurisdiction) and that you are authorized to enter into these Terms.
The Service helps you keep track of Google Calendar events by letting you mark them as complete or incomplete and view quick summaries inside the extension. Features may change as we continue to develop the product. Because the Service mirrors information from your Google account, you are responsible for verifying the accuracy of any calendar data before acting on it.
CalCheckr provides productivity tooling only. It does not offer legal, financial, employment, medical, or other professional advice, and you should not rely on any output of the Service to make critical or time-sensitive decisions without independently confirming the underlying information. Your use of the Service does not create any professional relationship between you and us, including legal, financial, employment, medical, or fiduciary relationships.
You acknowledge that the Service may modify Google Calendar event titles solely when you initiate an action (such as marking an event complete or incomplete) and that you are responsible for reviewing and confirming the accuracy of any edits before relying on them.
Some functionality may require a paid subscription. Details on current premium features and pricing are shown during checkout and may change.
A Google account is required to use the Service. You are responsible for keeping your account secure. The extension requests the minimum Google OAuth scopes needed to read your calendars, update event titles with completion markers, and identify your account. You can revoke these permissions at any time from your Google account settings or by disconnecting the extension inside the CalCheckr account settings, including at http://myaccount.google.com/connections.
CalCheckr operates the Service independently and is not created, supported, or endorsed by Google LLC. Your relationship with Google remains subject to Google’s own terms and policies, and you are solely responsible for complying with them.
You must maintain the confidentiality of your credentials, ensure devices running the extension are secure, and promptly notify us if you suspect unauthorized access to your account or billing information. We do not store Google Calendar event content.
Google API Limited Use Disclosure: Our use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
Please use the Service responsibly. In particular, do not:
If you choose a paid plan, billing is handled by Stripe. A free trial (no credit card required) lets you evaluate the Service before any charges apply. Trial duration may vary and will be displayed during activation. Once activated, your trial period and expiry date will be shown in your account. Once you upgrade, subscriptions renew automatically until cancelled. You can cancel anytime from the billing portal linked in your receipt, from the CalCheckr account settings inside the extension, or by contacting support before the next renewal. Cancellation takes effect at the end of the current billing period, and you will retain access until that period expires.
You are responsible for any taxes, duties, or levies associated with your purchase, other than taxes based on our net income.
After the free trial ends and a paid subscription begins, all fees are final and non-refundable because you have already had a risk-free opportunity to test the Service. Please make sure that the product meets your needs before the trial expires.
We may, at our sole discretion, issue refunds to correct billing errors or resolve technical issues that prevent you from using the Service as described. If you believe you qualify for an exception, contact support@calcheckr.com within 14 days of the charge so we can review your request.
Some jurisdictions do not allow certain refund limitations; in those places your rights provided by local law will apply.
By creating an account or starting a trial you agree that we may send you product updates, onboarding tips, billing notices, and essential security alerts. Marketing or educational emails include an unsubscribe link, and opting out of those messages does not affect the Service-related notices we must send (such as payment receipts or incident notifications).
If you opt in to newsletters or release announcements, we may send those messages using the email address associated with your account.
The Service is provided as-is, may change without notice, and may be discontinued if necessary. We aim to keep the extension reliable but cannot guarantee uninterrupted availability or compatibility with every browser configuration. Functionality may be limited or disabled if Google modifies its products, APIs, or policies, and we have no obligation to maintain deprecated features. We may discontinue the Service at any time, including if continued operation becomes infeasible due to platform changes.
We are not responsible for any loss, harm, or missed events resulting from outages, delays, data corruption, API limitations, or changes introduced by Google, Stripe, Sentry, or other third-party providers.
If you need help or have questions about the Service, email us at support@calcheckr.com. We try to respond promptly but response times can vary.
We may update these Terms from time to time as the Service evolves. When we make material updates we will post the new version here. Continuing to use the Service after changes take effect means you accept the updated Terms.
We may suspend or terminate your access immediately, without notice, if we detect abuse, unpaid invoices, or other violations of these Terms. You may stop using the Service at any time by uninstalling the extension and cancelling any active subscription. Sections that by their nature should survive termination (including payment obligations, disclaimers, and limitations of liability) will remain in effect.
We may also disable accounts if your use of the Service causes us to breach Google’s APIs or policies, harms the security or stability of other users, or exposes us to legal risk.
The Service is provided on an “as is” and “as available” basis. We make no warranties—express, implied, or statutory—about uptime, accuracy, or suitability for a particular purpose. Your use of the Service is at your sole risk, and you understand that extensions can be affected by changes to Google Calendar that are outside of our control.
Without limiting the foregoing, we do not warrant that the Service will preserve, synchronize, or display calendar information without loss, corruption, delay, duplication, or missed notifications. You are solely responsible for backing up your calendar data and confirming any edits the Service performs on your behalf. You acknowledge that the Service may modify Google Calendar event titles and agree to review the results before relying on them.
To the fullest extent permitted by law, CalCheckr and the individual operating the Service (together with any service providers acting on our behalf) will not be liable for indirect, incidental, special, consequential, or punitive damages, or any loss of profits or data, arising out of or related to your use of the Service, whether based in contract, tort, or otherwise. Our total cumulative liability for any claim will not exceed the amounts you paid for the Service in the twelve (12) months preceding the event giving rise to the claim.
These Terms are governed by the laws of the State of California, United States, without regard to conflict of law principles. You agree that no partnership, joint venture, or agency relationship exists between you and CalCheckr merely because you use the Service.
The Service integrates with platforms operated by third parties (such as Google, Stripe, and Sentry). Their terms and privacy practices govern any data they handle, and we are not responsible for their acts or omissions. Links to external resources are provided for convenience and do not constitute an endorsement. From time to time we may release beta or preview functionality that is identified as such; those features may be unreliable, may never graduate to production, and are provided without support or warranties. The Service is not intended to serve as a backup of your Google Calendar data, and you should maintain your own copies of any information that matters to you.
You agree to indemnify and hold harmless CalCheckr, the operator of the calcheckr.com domain, and any service providers who help deliver the Service from any claims, damages, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your use or misuse of the Service; (b) your violation of these Terms or applicable law; or (c) any content or data you submit to or through the Service.
You represent that you are not located in a jurisdiction where access to the Service is prohibited and that you are not on any U.S. government restricted list. You will comply with all applicable laws, regulations, and export controls, and will not use the Service for any unlawful purpose or to process data that you do not have a legal right to use.
These Terms constitute the entire agreement between you and CalCheckr regarding the Service and supersede any prior agreements. If any provision is found unenforceable, the remaining terms remain in effect. You may not assign these Terms without our prior written consent, and any attempted assignment is void. Our failure to enforce any right does not constitute a waiver of that right. Nothing in these Terms creates an employment, contractor, agency, fiduciary, or joint-venture relationship between you and us. Provisions that by their nature should survive termination (including payment obligations, disclaimers, indemnities, and limitations of liability) will survive.
Except for claims eligible to be brought in small-claims court (which either party may pursue), any dispute arising out of or relating to the Service or these Terms will be resolved through binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules. Arbitration will take place in San Francisco County, California, or another location we mutually agree on, and the arbitrator’s decision may be entered in any court with jurisdiction. The Federal Arbitration Act governs the interpretation and enforcement of this section. Arbitration may not apply where prohibited by law. Nothing in this section limits any rights you may have under applicable consumer protection laws.
YOU AND CALCHECKR AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING. UNLESS WE BOTH AGREE OTHERWISE, THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON’S CLAIMS OR OTHERWISE PRESIDE OVER ANY FORM OF A REPRESENTATIVE OR CLASS PROCEEDING.
If you opt out of arbitration by sending a written notice to support@calcheckr.com within 30 days of first accepting these Terms, or if the class-action waiver is found unenforceable, this entire section will be null and void and disputes will instead be resolved exclusively in the state or federal courts located in San Francisco County, California.
