Privacy Policy
Last updated: May 14, 2026
Introduction
Commerce Tally ("we", "our", or "us") operates the commercetally.com website. This page informs you of our policies regarding the collection, use, and disclosure of personal information when you use our service.
Commerce Tally is built as a public educational calculator hub for ecommerce sellers. The calculators are designed to run in your browser so visitors can estimate pricing, profit margin, marketplace fees, shipping costs, returns, inventory turnover, discounts, and sales tax arithmetic without creating an account.
Information Collection and Use
We collect minimal personal information. Our calculators perform all calculations in your browser, and we do not store or transmit your calculation data to our servers.
We may collect the following types of information:
- Usage data such as pages visited, time spent, and browser type
- Contact information if you contact us by email
- Cookies and similar tracking technologies used by advertising or analytics services
We do not ask users to upload store files, marketplace reports, tax returns, customer lists, or accounting records. If you voluntarily include business information in an email message, we use it only to understand and respond to that message.
Cookies and Advertising
We use Google AdSense to display advertisements. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.
Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to this site and/or other sites on the Internet.
Users may opt out of personalized advertising by visiting Google's Ads Settings. You can also visit aboutads.info to learn about opting out of some third-party vendors' uses of cookies for personalized advertising.
Third-Party Services
Google AdSense and other third-party vendors or ad networks may use cookies, web beacons, IP addresses, or other identifiers to help serve and measure ads.
Third-party providers may process data under their own privacy policies. Commerce Tally does not control how external advertising, analytics, hosting, browser, email, or security services operate. Review those providers directly if you want more detail about their data practices.
How We Use Information
We use limited information to operate the website, keep pages available, respond to visitor messages, understand which calculators and guides are useful, prevent abuse, improve content quality, and support advertising where applicable.
We do not sell calculation inputs. Because calculator math is performed locally in the browser, the ordinary use of a calculator does not require sending the values you type to a Commerce Tally database.
Data Retention
Contact emails may be retained for a reasonable period so we can respond to questions, follow up on bug reports, and maintain basic records of site feedback. Server, security, advertising, and analytics logs may be retained by service providers according to their own retention practices.
Data Security
The security of your data is important to us. We strive to use commercially acceptable means to protect your personal information, but remember that no method of transmission over the Internet or electronic storage is 100% secure.
Your Rights
You have the right to:
- Access the personal information we hold about you
- Request correction of inaccurate information
- Request deletion of your personal information
- Object to processing of your personal information
- Opt out of personalized advertising
Available rights can depend on your location and the type of information involved. If you contact us about a privacy request, we may need enough information to verify and process the request.
Children's Privacy
Commerce Tally is intended for general audiences and is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information, contact us so we can review the issue.
Changes to This Privacy Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
