1. Agreement Overview
This Agreement sets out the terms under which the Service Provider offers and you obtain access to the Premium Subscription Service. By subscribing or otherwise activating the Premium Subscription you confirm that you have read, understood, and agree to be bound by this Agreement and by the App’s Terms of Service and Privacy Policy. If you do not agree, do not subscribe and do not use the Premium Subscription.
2. Subscription Service Description
2.1 Service Content
The Premium Subscription provides enhanced features, services and/or content as set forth in the App. The precise content and functionality of the Premium Subscription are displayed in the App and may vary by geographic region, device type and platform. The Service Provider reserves the right to modify features, content, and functionality subject to the terms of this Agreement and applicable law.
2.2 Subscription Types
Where subscriptions are offered, the following rules apply to the plans shown at checkout:
Monthly subscriptions where shown at checkout;
Annual subscriptions where shown at checkout;
Any other billing period expressly shown at checkout; and
Any eligible trial or promotional offer disclosed with the selected plan.
Available subscription types, their durations, trial offers and promotional pricing (if any) will be shown at the point of sale within the App.
3. Payment and Billing
3.1 Payment Methods
For current Android subscriptions, Google Play processes payment and applies the billing cycle and payment method shown at checkout. We do not receive or store your payment card number.
3.2 Billing Cycle
Subscription fees are charged in advance and will be billed in accordance with the subscription period you selected. The exact amount and currency will be displayed at the time of purchase.
3.3 Price Changes
We reserve the right to change subscription prices. We will provide notice of price changes in accordance with applicable law and platform rules. A price change takes effect as shown by Google Play after applicable notice and any required consent. If you do not agree to the change, you may cancel the subscription prior to the next renewal.
4. Auto-Renewal Terms
4.1 Auto-Renewal Mechanism
A subscription automatically renews at the end of the selected billing period unless you cancel before renewal. Google Play charges the payment method for the purchase. Check Google Play for the next billing date and cancel there if you do not want to renew.
4.2 Promotional and Trial Period Terms
Trial Periods: If a free trial is offered, you will be informed of the trial length and any subsequent automatic billing. If you do not cancel before the trial period ends, the subscription will automatically convert to a paid subscription and you will be charged the applicable fee.
Limited-Time Promotional Pricing: A reduced price applies for the periods specified in the offer. After that, the subscription renews at the disclosed standard price unless canceled.
Trial + Promotional Combination: Where a trial is followed by promotional pricing the terms of both the trial and the promotion apply as described at the point of sale.
All promotional and trial terms will be clearly disclosed at the point of purchase.
4.3 Renewal Reminders
Renewal reminders are provided as required by applicable law and Google Play rules.
5. Cancellation and Refund Policy
5.1 Cancellation of Subscription
You may cancel your subscription at any time via the platform you used to purchase the subscription:
Google Play users: Open Google Play subscriptions with the Google Account used to purchase and select Cancel subscription.
If a subscription is offered through the Apple App Store, manage it in your Apple Account subscription settings.
Uninstalling the app does not cancel a Google Play subscription.
Cancellation must be completed in accordance with the platform’s procedures. If you cancel, access to Premium features will continue until the end of the current paid period unless applicable law or the platform provides otherwise.
5.2 Refund Policy
For Google Play purchases, see the Google Play refund policies. You can also contact us at support@nextaix.com for refund assistance or to request a remedy we are required to provide by law.
Statutory Rights: In certain jurisdictions, consumers have statutory rights (for example, a right to withdraw within a specified period). Such statutory rights apply in addition to the platform’s refund policy and cannot be waived by this Agreement. To the extent local mandatory law provides consumers with refund, withdrawal or cancellation rights that are more favorable than this Agreement, those statutory rights will apply.
5.3 Access Rights After Service Termination
After you cancel automatic renewal, Premium access normally continues until the end of the paid period, subject to applicable law and Google Play rules. When the period ends, access provided by that subscription ends. Separate purchase entitlements are governed by their own terms.
6. User Rights and Obligations
6.1 User Rights
During the effective paid subscription period you are entitled to:
Access and use the Premium features described in the App;
Cancel your subscription at any time; and
Exercise any consumer rights available under applicable law.
6.2 User Obligations
You agree to:
Provide accurate and current information to Google Play when making the purchase;
Comply with the App’s Terms of Service and this Agreement;
Keep payment information up to date and ensure sufficient funds/payment ability to avoid interruption of service.
You shall not misuse the Service, attempt to bypass platform controls (including trial or promotional restrictions), or use the Service in violation of applicable law.
7. Service Changes and Termination
7.1 Service Changes
We may change, suspend, or discontinue all or part of the Premium Subscription subject to Section 16 of the Terms of Service, including its grounds for action, notice requirements, and remedies if your access to or use of paid features is materially affected. Changes under that section are made at no extra charge. Subscription price changes are governed by Section 3.3 of this Agreement.
7.2 Account Termination
If you materially breach this Agreement, the Terms of Service or engage in fraudulent or abusive behavior, we may suspend or terminate your subscription and access to the App’s Premium features. The notice rules in Section 15 and the remedies in Section 16 of the Terms of Service apply. See Section 5.2 for refund requests and statutory rights. An access restriction does not itself cancel automatic renewal in Google Play. Termination for cause does not relieve you from obligations accrued prior to termination.
8. Regional Compliance
8.1 EU User Rights
Consumers in the EU or EEA may have a 14-day right to withdraw from a distance contract, subject to statutory conditions and exceptions. For digital content, starting performance may end that right only where the legal conditions are met. This right is separate from canceling renewal. Contact us using section 13 to exercise applicable statutory rights.
8.2 US User Rights
Users in the United States may have additional consumer protections under state and federal law. In particular, residents of certain states (such as California) may have additional privacy and consumer-protection rights (for example under CCPA/CPRA), which will be addressed in the Privacy Policy and implemented where applicable.
8.3 Other Regions
We will comply with applicable laws and regulations of the user’s jurisdiction where we provide services. Local mandatory consumer protection provisions (including refund/withdrawal rights and requirements regarding automatic renewal disclosures) will govern to the extent they conflict with this Agreement.
9. Data Protection and Privacy
The Privacy Policy explains how purchase and entitlement information is processed and how to exercise privacy rights. Google Play processes payments.
10. Disclaimers

To the maximum extent permitted by applicable law, the Service Provider’s aggregate liability to you for any and all claims arising out of or in connection with this Agreement shall not exceed the total subscription fees paid by you to the Service Provider in the twelve (12) months preceding the event giving rise to the claim (or such lesser amount as may be required by applicable law). To the extent permitted by applicable law, neither party shall be liable for indirect, incidental, special, consequential or punitive damages, even if advised of the possibility of such damages.

Nothing in this section shall limit liability for gross negligence, willful misconduct, or for any liability which cannot be excluded by applicable law.
11. Dispute Resolution
