In no event shall our total liability to you for all claims arising out of or related to the Service exceed one hundred U.S. dollars ($100.00) or the amount you paid us in the past twelve months, whichever is greater.
Some jurisdictions do not allow the exclusion of certain warranties or limitation of certain damages, so some of the above limitations may not apply to you.
You agree to defend, indemnify, and hold harmless GrowByMe, LLC from and against any claims, liabilities, damages, judgments, and expenses (including reasonable attorneys’ fees) arising out of or related to your violation of these Terms or your use of the Service.
These Terms are governed by the laws of the State of Texas, United States, without regard to its conflict-of-law provisions.
Before initiating formal legal proceedings, you agree to contact us at jr@jammin.chat and make a good-faith effort to resolve the dispute informally for at least 30 days.
Except for matters that may be brought in small claims court, any dispute, claim, or controversy arising out of or relating to these Terms or the Service shall be resolved exclusively by final and binding arbitration administered by the American Arbitration Association (AAA) under its applicable consumer arbitration rules.
The seat and venue of arbitration shall be Travis County, Texas, unless the parties agree otherwise. Judgment on the arbitration award may be entered in any court of competent jurisdiction.
30-day opt-out right: You may opt out of this arbitration provision by emailing jr@jammin.chat within 30 days of first accepting these Terms. Your opt-out notice must include your name, the email associated with your account (if any), and a clear statement that you want to opt out of binding arbitration. Opting out of arbitration does not affect any other part of these Terms.
You and GrowByMe, LLC also waive any right to a jury trial for any dispute that is determined to be non-arbitrable and proceeds in court.
If a court determines that this class action waiver is unenforceable for a particular claim or request for relief, that claim shall be severed and proceed only in the state or federal courts located in Travis County, Texas, and the remaining claims shall be arbitrated.
We may suspend or terminate your access to the Service at any time, with or without notice, for conduct that we believe violates these Terms or is harmful to other users, us, or third parties, or for any other reason at our discretion.
You may stop using the Service at any time. If you have an account, you may delete it through your account settings. Sections 7–19 of these Terms survive termination.
We may update these Terms from time to time. If we make a material change, we will post the updated Terms on this page and update the “Last updated” date. For registered users, we will also send a notice to the email address on file at least 30 days before material changes take effect.
Continued use of the Service after the effective date of any changes constitutes your acceptance of the new Terms.
The Service is intended for users located in the United States. We do not represent that the Service is appropriate or available in other jurisdictions. If you access the Service from outside the United States, you do so at your own risk and are responsible for compliance with local laws.
