Your CSV files
Files you open in the tool or the demo are read by your browser on your device. They are not sent to our server or to anyone else. The pages ask your browser to block connections to other sites while the tool runs, so a file cannot be sent out even by mistake.
What is stored on your device
The cost per unit you type for each listing is saved in your browser's local storage so you do not have to enter it again. It stays on your device. You can remove it with the "Clear saved costs" button or by clearing site data in your browser. Listing names are used as the key for these costs.
No tracking
We do not use analytics, advertising pixels or measurement tools on the site or the tool. We do not set cookies.
Fonts
Pages load fonts from Google Fonts. Google may see your IP address when your browser fetches them. The tool and demo page logic does not send your files there.
Payments
Payments are handled by Stripe. Stripe collects the payment details and your email address for the receipt, under its own privacy policy. We do not see your card number. We use the payment record to confirm your purchase and to give refunds.
If you write to us, we keep your message to answer you. We do not sell or share your data.
Your choices
To ask about data we hold (such as a payment record), email ege@appxiom.co.
