Privacy Policy
Overview
AppMargins (appmargins.com) is a free utility website that provides app store fee and revenue calculators for developers. This policy explains how we handle data when you use our tools.
Data We Collect
All calculations on AppMargins run entirely in your browser. No numbers, inputs, or results you enter are sent to our servers or stored anywhere outside your device. We do not collect personal information such as your name, email address, or financial account details.
We do collect anonymous usage data through Google Analytics 4 to understand how our tools are used — for example, which calculator tabs are most popular. This data is aggregated and not tied to any individual user.
Google AdSense
We display advertisements provided by Google AdSense. Google uses cookies and similar tracking technologies to serve ads based on your browsing history and interests. You can opt out of personalized advertising at adssettings.google.com. For more information, see Google's Privacy Policy.
Google Analytics
We use Google Analytics 4 to measure site traffic and usage. Google Analytics collects data such as pages visited, time on site, and general location (country/region). This data is anonymized and used solely to improve the site. You can opt out via the Google Analytics Opt-out Browser Add-on.
Cookies
AppMargins itself does not set first-party cookies. Google AdSense and Google Analytics may set third-party cookies to support advertising personalization and analytics. You can manage or delete cookies through your browser settings.
CCPA — California Residents
If you are a California resident, you have the right to know what personal information is collected about you, to request deletion of your personal information, and to opt out of the sale of personal information. AppMargins does not sell personal information. For any California privacy requests, contact us at privacy@vanilabs.co.
GDPR — European Users
If you are located in the European Economic Area, you have rights under the General Data Protection Regulation including the right to access, rectify, and erase your personal data. The lawful basis for processing analytics data is legitimate interest (understanding how our free tools are used to improve them). For GDPR inquiries, contact privacy@vanilabs.co.
Third-Party Links
AppMargins may contain links to external websites (such as app store documentation pages). We are not responsible for the privacy practices of those sites and encourage you to review their privacy policies.
Children's Privacy
AppMargins is not directed at children under 13. We do not knowingly collect any personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.
Changes to This Policy
We may update this policy periodically. The effective date at the top of this page will reflect the most recent revision. Continued use of the site after changes constitutes acceptance of the updated policy.
