PAYMENTS, TAXES, AND REFUNDS

Pricing and Currency

Base prices are set in U.S. dollars (USD) and may also be displayed in your local currency based on your location, where supported by our payment processor. You may pay in any currency offered at checkout, including USD, EUR, GBP, CZK, and other major currencies supported by Stripe. Currency conversion is handled by our payment processor at the prevailing exchange rate; your issuing bank may apply additional conversion or foreign-transaction fees, which are outside our control. Prices are subject to change with at least 30 days' notice for subscription changes; one-time prices may change at any time for new purchases.

Payment Processing

Payments are processed by Stripe, Inc. (and, where applicable, by other third-party providers such as PayPal). Supported payment methods include major credit and debit cards (Visa, Mastercard, American Express, Discover), Apple Pay, Google Pay, and region-specific methods such as SEPA Direct Debit (EU), iDEAL (Netherlands), Bancontact (Belgium), and others made available by the payment processor. We do not store or have direct access to your full payment card details; these are handled by the payment processor under PCI-DSS standards. By submitting payment information, you authorize the payment processor to charge your selected payment method for the amounts you owe us.

Taxes

Prices are quoted excluding taxes. The Operator is not registered as a VAT payer in the Czech Republic (neplátce DPH). For customers in jurisdictions where we or our payment processor are required to collect indirect taxes (such as U.S. state sales tax, EU VAT on cross-border digital services, GST, or similar), applicable taxes will be added at checkout and remitted in accordance with the relevant law. You are responsible for any import duties, use taxes, or other taxes not collected at checkout.

Subscriptions and Recurring Billing

Subscriptions auto-renew at the end of each billing period (monthly or annual, as selected) until cancelled. You authorize us and our payment processor to charge your payment method on a recurring basis for subscription fees, applicable taxes, and any fees associated with changes to your plan. You may cancel at any time through your account settings or by contacting us; cancellation takes effect at the end of the current billing period.

Refunds

Refunds are provided as follows:

• EU consumers: you have a statutory 14-day right of withdrawal from distance contracts under Czech Act No. 89/2012 Coll. (Civil Code) and EU Directive 2011/83/EU. This right does not apply to digital content that has been delivered and with which you have begun interacting after expressly consenting to immediate delivery and acknowledging loss of the right of withdrawal, in accordance with Article 16(m) of Directive 2011/83/EU.
• U.S. customers: outside of applicable statutory requirements, refunds are provided at our discretion. For subscription purchases, we generally refund the most recent billing cycle on good-faith request within 14 days. For one-time purchases of digital content that has been accessed or downloaded, all sales are final unless required otherwise by applicable state consumer-protection law.
• Payment disputes: before initiating a chargeback, please contact us to resolve the issue. Unjustified chargebacks may result in suspension of your account.

Failed Payments

If a recurring payment fails, we may retry the charge, suspend your access until payment is resolved, or terminate your subscription. You are responsible for keeping your payment information current.

DISCLAIMERS

THE EXTENSION IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT, TO THE FULLEST EXTENT PERMITTED BY LAW. Nothing in this section limits warranties that cannot be excluded under mandatory Czech, EU, or U.S. state law (including implied warranties of merchantability and fitness for a particular purpose in U.S. states that do not permit their exclusion).

TERM AND TERMINATION

You may stop using the Extension at any time by uninstalling it. We may suspend or terminate your access for breach of these Terms, fraudulent or illegal activity, abuse, or failure to pay. Upon termination, your license ends, but provisions that by their nature survive (IP, disclaimers, liability limits, dispute resolution) remain in effect.

MODIFICATIONS

We may update these Terms. Material changes will be notified via the Extension, email, or our website at least 30 days in advance for subscription users. Continued use after the effective date constitutes acceptance. If you do not accept the new Terms, you must stop using the Extension.

GOVERNING LAW AND DISPUTE RESOLUTION

Governing Law

These Terms are governed by the laws of the Czech Republic and applicable European Union law, without regard to conflict-of-law principles. This choice of law does not deprive consumers of the protections of mandatory provisions of the law of their country of habitual residence. If you are a consumer residing in a U.S. state, the mandatory consumer protection laws of your state of residence shall apply to the extent they cannot be waived by contract.

Informal Dispute Resolution

Before filing any formal claim, the parties agree to attempt good-faith informal resolution for at least thirty (30) days after written notice. Notices to us should be sent to the contact email listed in the “Contact” section.

Jurisdiction and Venue

Subject to any mandatory consumer jurisdiction rules that give consumers the right to sue or be sued in the courts of their place of residence:

• EU and other international users: any dispute shall be submitted to the exclusive jurisdiction of the competent courts of the Czech Republic, with Prague as the venue
• U.S. users — individual claims only: you and the Operator agree that any dispute arising from these Terms or your use of the Service shall be resolved on an individual basis. Class actions, class arbitrations, and representative actions are waived to the fullest extent permitted by law. This waiver does not apply to small-claims court actions or to claims that cannot be waived under applicable mandatory law.

Out-of-Court Consumer Dispute Resolution

Consumers in the EU may refer disputes to the Czech Trade Inspection Authority (Česká obchodní inspekce), the competent out-of-court consumer dispute resolution body in the Czech Republic, via www.coi.cz. EU residents may also use the European Commission's Online Dispute Resolution platform at https://ec.europa.eu/consumers/odr.

Exceptions

Notwithstanding the above, either party may bring an action in any court of competent jurisdiction for (a) injunctive or equitable relief to protect intellectual property rights, (b) claims alleging theft, piracy, invasion of privacy, or unauthorized use, and (c) claims seeking only small-claims-court relief.

U.S. FEDERAL AND STATE-SPECIFIC PROVISIONS

Export Controls and Sanctions (OFAC)

The Service may be subject to U.S. export control and economic sanctions laws, including those administered by the U.S. Office of Foreign Assets Control (OFAC) and the U.S. Department of Commerce. You represent and warrant that: (i) you are not located in, under the control of, or a national or resident of any country subject to comprehensive U.S. sanctions (currently including Cuba, Iran, North Korea, Syria, and the Crimea, Donetsk, and Luhansk regions of Ukraine); and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties, including the Specially Designated Nationals List.

Section 230 of the Communications Decency Act

To the extent applicable, we rely on the protections of Section 230 of the U.S. Communications Decency Act, 47 U.S.C. § 230, with respect to any user-generated content transmitted through the Service. We reserve the right, but have no obligation, to monitor, remove, or edit user content in our discretion.

Electronic Signatures (E-SIGN Act and UETA)

You consent to receive communications from us electronically and agree that electronic acceptance of these Terms, electronic records, and electronic signatures have the same legal effect as handwritten signatures, in accordance with the U.S. Electronic Signatures in Global and National Commerce Act (E-SIGN Act), the Uniform Electronic Transactions Act (UETA), and equivalent provisions of Czech and EU law.

California Consumer Notice

No Industry-Specific Compliance

The Service is not designed to comply with industry-specific U.S. regulations such as the Health Insurance Portability and Accountability Act (HIPAA), the Gramm-Leach-Bliley Act (GLBA), or the Family Educational Rights and Privacy Act (FERPA). You may not use the Service to transmit protected health information, non-public financial information, or student records subject to these laws.

MISCELLANEOUS
