If you are a California resident, you hereby waive California Civil Code Section 1542, which states: "A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party."
We may, at our sole discretion, suspend, restrict, or terminate your access to the Services, in whole or in part, at any time, for any reason or no reason, with or without prior notice or liability to you.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICES ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED. WE EXPRESSLY DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, QUIET ENJOYMENT, NON-INFRINGEMENT, AND AVAILABILITY, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING, COURSE OF PERFORMANCE, OR USAGE OF TRADE.

THE SERVICES ARE NOT DESIGNED TO PROVIDE MEDICAL, HEALTH, OR THERAPEUTIC ADVICE. THE SERVICES ARE INTENDED SOLELY FOR ENTERTAINMENT AND EDUCATIONAL PURPOSES.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE COMPANY, ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, PARTNERS, SUPPLIERS, OR LICENSORS BE LIABLE TO YOU OR ANY THIRD PARTY FOR ANY:
ARISING OUT OF OR RELATING TO THESE TERMS OR YOUR USE OF (OR INABILITY TO USE) THE SERVICES, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, OR ANY OTHER LEGAL THEORY, WHETHER OR NOT WE HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGE, AND EVEN IF A REMEDY SET FORTH HEREIN IS FOUND TO HAVE FAILED OF ITS ESSENTIAL PURPOSE.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE AGGREGATE (TOTAL) LIABILITY OF THE COMPANY, ITS AFFILIATES, AND ITS LICENSORS TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR YOUR USE OF THE SERVICES SHALL NOT EXCEED THE LESSER OF: (A) THE TOTAL AMOUNT ACTUALLY PAID BY YOU TO THE COMPANY IN THE SIX (6) MONTHS IMMEDIATELY PRECEDING THE DATE ON WHICH YOU FIRST ASSERT ANY SUCH CLAIM; OR (B) TWENTY UNITED STATES DOLLARS (US$20.00).
IN THE EVENT THAT YOU ASSERT ANY CLAIM SEEKING STATUTORY DAMAGES OR PENALTIES, YOU AGREE TO WAIVE ANY RIGHT TO STACK OR COMBINE THOSE STATUTORY DAMAGES OR PENALTIES WITH ANY OTHER DAMAGES OR CLAIMS.
The limitations in this section apply regardless of the theory of liability, including but not limited to breach of contract, tort (including negligence), strict liability, or any other basis, and shall apply even if the Company has been advised of the possibility of damages and even if any remedy fails of its essential purpose. Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above limitations may not apply to you. In such cases, our liability will be limited to the fullest extent permitted by applicable law.
To the maximum extent permitted by applicable law, you agree to defend, indemnify, and hold harmless the Company, its affiliates, and their respective officers, directors, employees, agents, licensors, suppliers, partners, and successors from and against any and all claims, demands, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees and legal costs) arising out of or in any way connected with:
We reserve the right, at your expense, to assume the exclusive defense and control of any matter subject to indemnification by you, and you agree to cooperate with our defense of such claims. You agree not to settle any such matter without our prior written consent.
PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES YOU TO FOLLOW A PRE-DISPUTE NOTICE PROCESS BEFORE FILING MOST CLAIMS.
Before initiating formal legal proceedings, you agree to first send us a written Notice of Claim at the email address listed in the Contact section. The Notice must include: (a) your full name; (b) your account email (if any); (c) your mailing address; (d) a detailed statement of facts and legal basis; and (e) the specific relief requested. The parties will attempt in good faith to resolve the dispute for thirty (30) days from receipt of the Notice. No party may file a formal action during this period, except to seek urgent injunctive relief.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, YOU AND THE COMPANY AGREE THAT CLAIMS MUST BE BROUGHT ONLY IN AN INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, COLLECTIVE, CONSOLIDATED, REPRESENTATIVE, OR MASS ACTION.
If this individual-only claims provision is found unenforceable for a specific claim, that claim shall proceed only to the extent required by applicable law, and all remaining provisions of these Terms shall remain in effect.
Nothing in these Terms prevents either party from seeking temporary, preliminary, or injunctive relief in a court of competent jurisdiction to protect intellectual property, confidential information, platform integrity, or security while a dispute is pending.
Nothing in this Section limits any non-waivable consumer rights, including your right to apply to competent consumer authorities, arbitration committees, or courts where such rights cannot lawfully be restricted.
YOU AGREE THAT ANY CLAIM YOU MAY HAVE ARISING OUT OF OR RELATING TO THESE TERMS OR YOUR RELATIONSHIP WITH US MUST BE FILED WITHIN ONE (1) YEAR AFTER THE DATE ON WHICH SUCH CLAIM FIRST AROSE. OTHERWISE, YOU ACKNOWLEDGE AND AGREE THAT YOUR CLAIM WILL BE PERMANENTLY BARRED AS UNTIMELY. THIS LIMITATION SHALL APPLY REGARDLESS OF WHETHER THE CLAIM IS BASED IN CONTRACT, TORT, STATUTE, OR ANY OTHER LEGAL THEORY. THIS SECTION DOES NOT APPLY WHERE PROHIBITED BY APPLICABLE LAW.
These Terms and any non-mandatory dispute arising out of or relating to these Terms or the Services shall be governed by and construed in accordance with the laws of the Republic of Turkiye, without regard to conflict-of-law principles. Subject to mandatory consumer protection laws, disputes shall be submitted to the Istanbul Anadolu Courts and Enforcement Offices.

You may not assign, transfer, or delegate your rights or obligations under these Terms without our prior written consent. We may freely assign, transfer, or delegate our rights and obligations under these Terms without restriction, including in connection with a merger, acquisition, reorganization, or sale of all or substantially all of our assets.

No employee or agent of the Company is authorized to modify these Terms orally or in writing. Only a formal amendment posted on our Services or sent to you directly shall constitute a modification of these Terms.
We shall not be liable for any failure or delay in performing our obligations under these Terms where such failure or delay results from circumstances beyond our reasonable control, including but not limited to acts of God, natural disasters, war, terrorism, riots, embargoes, acts of civil or military authorities, fire, floods, epidemics, pandemics, internet failures, network infrastructure failures, computer viruses, cyber attacks, strikes, or shortages of transportation, facilities, fuel, energy, labor, or materials.
