Privacy Notice

Your calling lists stay in your browser unless you use them with Quo, export them, or choose to share them. Our website, account, and billing services handle other information as explained below.

1. Who this notice covers

This notice covers zavrenn.com, Zavrenn Power Dialer, and our account and support services. Zavrenn is the trading brand of an independently operated sole-proprietor software business. The Zavrenn operator is responsible for the personal information it processes for these services. For privacy questions or requests, email [email protected].

2. Calling data stored in your browser

The extension stores imported contacts, phone numbers, names, companies, identifiers, imported notes, queues, outcomes, call notes, Do Not Call entries, settings, and call history in local browser storage. Zavrenn’s account and billing backend does not receive your imported contact lists or call notes. We do not use your local calling data to train AI models.

When you place a call, the extension passes the selected number and relevant calling actions to Quo. Quo processes calls and associated information under its own terms and privacy policy. “Local storage” does not mean that a phone call happens without sending a number to your phone provider. Files you export or back up contain the data you choose to include; anyone you share them with may be able to read them. If you send us a screenshot or diagnostic file for support, we receive whatever information it contains.

3. Account, device, billing, launch-list, and support information

When you use account-enabled features, we process your email address, account identifier, authentication and verification information, and subscription status. Device registration uses a random installation identifier, device label, coarse platform/browser information, extension version, and activation or last-seen timestamps. Limited service events, such as device activation, opening checkout or the billing portal, and starting an entitled session, help us operate access controls and support the service. They do not include the contents of your call list or notes.

Stripe collects payment details, billing information, and information needed for payments, fraud prevention, and tax obligations. We receive subscription/customer identifiers, payment and subscription status, and related transaction information needed to administer access and support. Full payment-card details are entered into Stripe Checkout, not into the extension or our own payment form.

If you contact us, we receive your email address, correspondence, and any information you choose to send. Please do not send payment-card numbers, passwords, complete contact lists, or sensitive call notes.

If you join the Zavrenn launch list, we store the name and email address you submit in this website’s WordPress database so we can send product launch updates. We do not add launch-list submissions to your extension account or calling data.

4. Website logs, cookies, analytics, and advertising

Your cookie choices

For visits identified in the United States, optional analytics, session replay, and advertising are enabled by default unless you have saved a different choice or send a Global Privacy Control signal. For other countries, or when we cannot verify the region, optional tracking remains off until you enable it. We use country information supplied by our delivery provider from the network address, not precise browser location. IP-based country estimates can be affected by VPNs and network routing. A regional default is not stored as an affirmative consent choice. Use the cookie banner to accept or reject all optional categories. To choose analytics, session replay, and advertising separately, open Cookie settings in the footer. Essential security and core site functions remain available regardless of your choice. You can reopen Cookie settings in the footer on any page to change or withdraw consent. Saving your choices reloads the page so both browser and server-side tracking restrictions take effect.

We store your choice in a first-party cookie called zavrenn_consent for up to 180 days. It records the policy version, choice time, and selected categories, not a unique visitor identifier. Analytics controls Google Analytics and Cloudflare website measurement; session replay controls Microsoft Clarity, including its server-side visitor analytics; advertising controls Google Ads and advertising consent passed to Clarity. A browser Global Privacy Control signal keeps all optional tracking off, including when you previously enabled it. If you reject optional tracking, those optional tools are not loaded; ordinary hosting, security, and delivery logs are separate from website analytics.

When you withdraw a category, we remove known first-party tracking cookies for that category where accessible and reload to stop its code running. We cannot delete cookies belonging to other domains or reverse information already sent while tracking was enabled; you can use browser and provider controls for those. Clearing the preference cookie or allowing it to expire returns the website to the regional defaults described above and displays the banner again.

The website’s hosting and security services process technical information such as IP addresses, requested URLs, timestamps, referring pages, browser/device information, and request errors. The website also uses Google Analytics and Google Ads tags through Google Site Kit, Microsoft Clarity, and Cloudflare analytics. These website tools are separate from the extension’s local calling-data storage.

• Google Analytics and Google Ads: process website visits, device/browser details, referral information, identifiers, and interactions to measure traffic and advertising performance. Google tags may also support advertising and remarketing.
• Microsoft Clarity: captures website interactions through behavioral metrics, heatmaps, and session replay to help us understand how the website is used and improve it. Data may be collected using cookies and similar technologies. Microsoft may also use this information for its own purposes as described in its privacy statement.
• Cloudflare: helps deliver and protect the website and measures site performance and visits.

These tools may use cookies, browser storage, or similar identifiers. Website analytics do not grant those providers access to the extension’s private local storage. Browser privacy settings and content blockers can limit tracking; blocking essential storage may affect account or website functionality. You can also use Google’s Analytics opt-out tool and Google’s advertising controls. Clearing cookies does not cancel a subscription.

Depending on the law that applies to you, disclosures to advertising providers may be considered “sharing” or processing for targeted advertising. Contact us to request an applicable opt-out or ask about the website’s tracking. This notice describes data practices; reading or using the website is not, by itself, consent to tracking where affirmative consent is required.

5. Why we use information

We use information to provide accounts and subscription access, process and support purchases, send authentication, service, and requested launch messages, respond to questions, prevent abuse, protect the service, understand website use, measure advertising, and meet legal obligations. Where a law requires a legal basis, we rely as applicable on performing a contract, complying with law, legitimate interests in operating and securing the business, and consent for activities that require it. You may withdraw consent without affecting prior lawful processing.

6. Service providers and disclosures

Supabase provides account authentication, application database, and access-control services. Resend supports account and transactional email. Stripe provides payment processing and subscription management. We do not send your local calling lists to these account, email, or billing providers.

Hosting, security, email, analytics, and payment providers receive information needed for the purposes described here. Some, including payment and advertising providers, may act as independent controllers for their own legal or service purposes. We may also disclose information when required by law, to protect rights and security, or as part of a business transfer subject to applicable privacy obligations.

Provider notices: Supabase, Resend, Stripe, Google, Microsoft, Cloudflare, and Quo.

7. Retention and international processing

Local calling data remains on your device until you remove it, clear the relevant browser storage, or uninstall the extension. Exported files remain wherever you save them. We retain launch-list names and email addresses until you unsubscribe, ask us to delete them, or they are no longer needed for launch communications. We retain online account and support information for as long as needed to provide the service and address support, security, or legal matters. Billing, tax, dispute, and fraud-prevention records may be retained after account closure where necessary or required by law. Provider logs and backups may have separate retention cycles; removal from backups may not be immediate.

Service providers may process information in the United States or other countries whose laws differ from yours. Where applicable law requires safeguards for international transfers, the relevant legal protections and provider transfer arrangements apply. Contact us for information about a particular request or transfer.

8. Your choices and privacy rights

You can export or delete local calling data using the extension’s controls. Signing out or deactivating a browser is not the same as deleting local data, closing your online account, leaving the launch list, or canceling billing. For launch-list removal, online-account deletion, access, correction, portability, restriction, objection, or an applicable advertising opt-out, email [email protected]. We may need proportionate identity verification and will respond within the period required by applicable law. Some records may need to be retained for legal reasons.

When requesting account deletion, tell us if you also want your subscription canceled so future billing can be stopped. Deleting local data or uninstalling alone does not stop billing. Depending on your location, you may have a right to appeal a privacy-request decision or complain to a data-protection authority. Contact us for an appeal; exercising applicable privacy rights will not result in unlawful discrimination.

9. Security, children, and changes

We use reasonable technical and organizational measures to protect information, but no system is completely secure. Protect your device, account credentials, and exported files. Zavrenn is intended for adults using business software, not children under 18. Contact us if you believe a child has supplied personal information to us. We will update this notice and its effective date when practices change, and provide additional notice where required.
