7. Billing and Auto-Renewal

1. All payments are processed through Apple App Store or Google Play Store in-app purchases. The Company does not directly collect or store your payment card information.
2. Auto-Renewal Disclosure (California Automatic Renewal Law Compliance):
   • Monthly and annual subscriptions automatically renew at the end of each billing period at the then-current subscription price unless you cancel before the renewal date.
   • PRO Monthly: Your subscription will automatically renew every month at $9.99/month until you cancel.
   • PRO Annual: Your subscription will automatically renew every year at $59.99/year until you cancel.
   • You will be charged through your original payment method (Apple App Store or Google Play Store) on the same date each billing period.
   • To avoid being charged for a renewal period, you must cancel auto-renewal at least 24 hours before the end of the current billing period.
3. Renewal Reminder: We or the applicable app store will provide any renewal reminder required by applicable law. For annual subscriptions sold to California consumers, the required reminder will be provided within the legally required window before renewal. The store subscription-management screen shows the renewal date, renewal amount, and cancellation method.
4. Price Changes: We or the applicable app store will provide advance notice of a subscription price increase within the period required by applicable law and store policy. If you do not agree to the new price, you may cancel before it takes effect.
5. Affirmative Consent: By tapping "Subscribe," "Start Free Trial," "Purchase," or any similar confirmation button, you acknowledge that you have read and agree to the auto-renewal terms set forth in this Section 7 and expressly authorize recurring charges to your payment method until you cancel.

8. Free Trial

1. Eligible users may be offered a seven-day free trial for either PRO Monthly or PRO Annual. Actual eligibility, the trial end date, the first paid billing date, and the applicable price are determined and displayed by the Apple App Store or Google Play Store at the time of purchase, and that purchase-screen disclosure controls.
2. By starting a free trial, you acknowledge and agree that your subscription will automatically convert to a paid plan at the end of the trial period unless you cancel before the trial expires, at the price of the plan you selected: $9.99/month for PRO Monthly, or $59.99/year for PRO Annual. No further notice or consent is required for the automatic conversion beyond this disclosure and your initial consent at sign-up.
3. What You Will Be Charged: If you do not cancel before the trial ends, you will be charged the price of the plan you selected ($9.99 for PRO Monthly or $59.99 for PRO Annual) on the day immediately following the end of your trial, and that amount will recur each subsequent billing period until you cancel.
4. We or the applicable app store will provide any trial-expiration or paid-conversion notice required by applicable law or store policy. You can review the trial end date, first paid billing date, renewal price, and cancellation method on the purchase screen and in the store's subscription-management screen.
5. No charge is incurred if you cancel during the trial period. You will retain access to PRO features until the trial period expires.
6. Free trial eligibility is determined by the applicable app store and may be limited based on prior trial or subscription history associated with the relevant Apple ID or Google account.
7. Refund eligibility and timing for an App Store or Google Play purchase are determined by the applicable store. DAYWIKA will promptly provide reasonable assistance through contact@daywika.com.

9. Cancellation

How to Cancel:

• Apple (iOS): Go to Settings > Apple ID > Subscriptions > DAYWIKA > Cancel Subscription. Alternatively, you may cancel through your Apple ID Settings > Subscriptions at any time.
• Google (Android): Go to Google Play Store > Profile > Payments & subscriptions > Subscriptions > DAYWIKA > Cancel. Alternatively, you may cancel through Google Play Store > Subscriptions at any time.

Important Cancellation Information:

1. Cancellation takes effect at the end of the current billing period. You will retain access to PRO features until the end of the period you have already paid for.
2. Deleting the app does not cancel your subscription. You must cancel through your store settings as described above.
3. If you cancel during a free trial, the cancellation prevents the first paid charge. Unless the applicable store states otherwise, access to PRO features continues until the trial expires.
4. After cancellation, your account will revert to the Free plan. No learning data is deleted; vocabulary exceeding the Free custom-word limit will simply be excluded from automatic review.
5. You may re-subscribe at any time through the app.

10. Refunds

All subscription payments are processed through Apple App Store or Google Play Store in-app purchases. Refund eligibility, method, and timing are generally determined by the applicable store. DAYWIKA does not control a store's refund decision, but will promptly provide reasonable assistance where required by law.

1. There is no general federal statutory cooling-off period for these digital subscriptions. During a free trial, you may cancel before the trial ends to prevent the first paid charge. After a charge, request a refund through the applicable store.
2. Store refund channels:
   • Apple App Store: reportaproblem.apple.com
   • Google Play Store: play.google.com/store/account
3. Direct Assistance: If applicable law requires DAYWIKA to handle a request directly, contact contact@daywika.com. We will respond without undue delay and coordinate with the store or payment provider where necessary.
4. Billing Errors: If an overcharge results from the Company's action, we will support correction or refund in accordance with applicable law and the store's process. Reasonable costs caused solely by information supplied incorrectly by the user may be allocated only where permitted by law.

11. Downgrade

When switching from PRO to Free, your registered vocabulary data is retained but words exceeding the Free custom-word limit will be excluded from automatic review. No data is deleted, and all data is instantly restored upon re-subscription.

6. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES. IN SUCH JURISDICTIONS, THE COMPANY'S LIABILITY SHALL BE LIMITED TO THE MAXIMUM EXTENT PERMITTED BY LAW.

17. Indemnification

1. Your Obligation: You agree to indemnify, defend, and hold harmless the Company, its officers, directors, employees, agents, and affiliates (collectively, "Indemnified Parties") from and against any and all claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees and court costs) arising out of or relating to:

3. Limitation: Your indemnification obligation shall not apply to the extent that a claim arises from the Company's own gross negligence, willful misconduct, or breach of these Terms.

18. Binding Arbitration

The parties shall first attempt to resolve any dispute through good-faith negotiation for a period of at least thirty (30) days before initiating arbitration.

1. Agreement to Arbitrate: You and the Company agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service shall be resolved by binding individual arbitration administered by the American Arbitration Association ("AAA") under its Commercial Arbitration Rules and, where applicable, the Supplementary Procedures for Consumer-Related Disputes.
2. Delegation: The arbitrator, and not any federal, state, or local court or agency, shall have exclusive authority to resolve any dispute relating to the interpretation, applicability, enforceability, or formation of this arbitration agreement, including any claim that all or any part of this arbitration agreement is void or voidable.
3. Class Action Waiver: YOU AND THE COMPANY EACH WAIVE THE RIGHT TO A TRIAL BY JURY AND THE RIGHT TO PARTICIPATE IN A CLASS ACTION, COLLECTIVE ACTION, OR REPRESENTATIVE ACTION. All claims must be brought in an individual capacity only. Neither you nor the Company may seek to have any dispute heard as a class action, private attorney general action, or in any other proceeding in which either party acts or proposes to act in a representative capacity.
4. Small Claims Exception: Notwithstanding the above, either party may bring an individual action in small claims court for claims within that court's jurisdiction, provided the claim does not exceed $10,000 and is brought on an individual (non-class, non-representative) basis.
5. Opt-Out Right: You may opt out of this arbitration agreement by sending written notice to contact@daywika.com within 30 days of creating your account. Your notice must include your name, email address associated with your account, and a clear statement that you wish to opt out of the arbitration agreement. If you opt out, you and the Company retain the right to litigate disputes in court.
6. Arbitration Fees: Each party shall bear its own attorneys' fees. The Company will pay all AAA filing fees and arbitrator compensation for claims where the amount in controversy is under $10,000. For claims above $10,000, arbitration fees and costs shall be allocated in accordance with the AAA's applicable rules. If the arbitrator finds that either the substance of your claim or the relief sought is frivolous or brought for an improper purpose, then the allocation of fees shall be governed by the AAA rules.
7. Mass Arbitration Procedures: If twenty-five (25) or more similar arbitration demands are filed against the Company by or with the assistance of the same law firm, group of law firms, or organization within a sixty (60) day period ("Mass Filing"):
   • (a) Bellwether Process: The parties shall randomly select ten (10) individual claims from the Mass Filing to proceed as bellwether cases. The remaining claims shall be stayed pending resolution of the bellwether cases.
   • (b) Selection: The bellwether claims shall be selected by the AAA (five chosen by claimants' counsel and five by the Company). Each bellwether case shall be assigned to a separate, individual arbitrator.
   • (c) Resolution of Remaining Claims: Following resolution of the bellwether cases, the parties shall engage in a single mediation session of all remaining claims. If the remaining claims are not resolved through mediation, each remaining claim may proceed in individual arbitration, with the results of the bellwether cases informing, but not binding, the resolution of remaining claims.
   • (d) Fees for Mass Filings: The Company shall not be required to pay filing fees for more than ten (10) arbitration demands at a time during a bellwether process. Filing fees for stayed claims shall not be assessed until such claims are designated to proceed.
   • (e) Tolling: Any applicable statute of limitations shall be tolled for all claims subject to the Mass Filing stay from the date the first bellwether case is selected until the stay is lifted for each respective remaining claim.
8. Location: Any arbitration hearing shall take place in New Castle County, Delaware, or, at your election, may be conducted by videoconference or telephone.
9. Enforceability: If any portion of this arbitration agreement (other than the class action waiver) is found to be unenforceable, the remainder of this arbitration agreement shall remain in full force. If the class action waiver is found to be unenforceable, then this entire arbitration agreement shall be null and void, and disputes shall proceed in court pursuant to Section 19.

19. Governing Law and Jurisdiction

1. Governing Law: These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to its conflict of law provisions or principles.
2. Jurisdiction: For any disputes not subject to binding arbitration (including if you have validly opted out of arbitration), you and the Company consent to the exclusive jurisdiction and venue of the state courts located in New Castle County, Delaware, or the United States District Court for the District of Delaware.
3. Waiver of Objections: Each party waives any objection to jurisdiction and venue in the courts identified above, including any objection based on inconvenient forum.

20. Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, such invalidity, illegality, or unenforceability shall not affect any other provision of these Terms. The remaining provisions shall continue in full force and effect, and the invalid provision shall be modified to the minimum extent necessary to make it valid and enforceable while preserving the parties' original intent.

21. Force Majeure

Neither party shall be liable for any failure or delay in performing its obligations under these Terms where such failure or delay results from circumstances beyond the reasonable control of that party ("Force Majeure Event"), including but not limited to: natural disasters (earthquakes, floods, hurricanes, wildfires); war, terrorism, or armed conflict; riots, civil unrest, or insurrection; embargoes or sanctions; acts of civil or military authorities; fire; epidemics, pandemics, or public health emergencies; strikes, labor disputes, or work stoppages; shortages of transportation, facilities, fuel, energy, labor, or materials; power outages or telecommunications failures; cyberattacks or Internet service disruptions; or acts of God. The affected party shall use reasonable efforts to mitigate the effect of the Force Majeure Event and shall promptly notify the other party of the event and its expected duration. If a Force Majeure Event continues for more than sixty (60) consecutive days, either party may terminate these Terms upon written notice to the other party.
