OctoResell is built to work without collecting your data. This page explains the little that is stored and why.

In the extension

When you import a listing, OctoResell reads the listing's public details (title, description, price, brand, size, condition and photo links) from the page in your browser and saves them in your browser's local extension storage. When you crosslist, it downloads that listing's photos from the marketplace's image servers and fills in the listing form in your browser. Your listings, the pages you visit and your marketplace accounts are never sent to us.

When the same item is listed on two or more marketplaces, OctoResell checks those listings about every 15 minutes while your browser is open, to see whether one has sold. If you turn on automatic removal, or confirm a sale, it removes the other listings on your behalf. These checks and removals go straight from your browser to the marketplace, using the account you're signed in to there. To make those requests, the extension reads the marketplace's own session cookies on that marketplace's site. It never reads cookies from any other site, and never sends them to us.

The AI features are off by default. If you turn them on and add your own Google Gemini API key, the listing you're working on (its text, and its photos if you choose) is sent to Google's Gemini API to suggest titles and descriptions, under Google's terms. Your key is kept in the extension's background storage and is only sent to Google.

The extension also stores your settings, how many free crosslists you've used today, and your license key and activation ID if you have Pro. Uninstalling the extension deletes all of it.

License checks

When you activate Pro, and about once a day after that, the extension sends your license key and activation ID to our license service to confirm the license is valid. With Pro, the extension also sends a daily count of how many forms it filled, how many listings it imported and how many fills or imports failed, with the extension version. These are numbers only: no listing details, pages or marketplace data. We use them to find problems and improve OctoResell.

Install check-ins

On every plan, free included, the extension checks in with our service a few times a day. It sends a random ID created for your browser, the extension version, the browser name and version, the operating system, the browser language, your plan, how many listings you keep in OctoResell, the daily counts of fills, imports and failures described above, whether a Gemini key is connected (never the key itself), a daily count of how many times each feature was used and whether it worked (for example "crosslist: 4 worked, 1 failed", with no listing details), and a short note for each failure: the marketplace, the step that failed (for example a fill, an import or a sale check), the marketplace page path without any query string, the names of form fields that could not be filled, and the error message. Our service adds the country your request comes from. It never sends listing details, the pages you visit or anything from your marketplace accounts. We use this to count active users, see which versions and browsers run into problems, and prioritise fixes. When you remove the extension, the goodbye page records that this ID was removed.

Form layout with failure reports

When a fill leaves fields for you, or an import or sale check fails, the failure note can also carry diagnostics so we can fix it without guessing. For a fill, that is the layout of the marketplace's sell form: the names, ids, roles and labels of its fields, buttons and menus, the options a menu showed (marketplace lists such as categories, sizes and brands), which fields were already filled (yes or no only), how long each step took, whether the tab was in the background, and the item's category, brand, size and condition so we can see which choice was missing. For an import or sale check, it is whether it ran in the background or in a marketplace tab, why it switched, whether the tab was loading, closed or put to sleep by the browser, and the page path with ids removed. It never includes what you or OctoResell typed into a field, your titles, descriptions, prices or photos, messages, order or buyer details, usernames, email addresses, phone numbers or cookies. Text matching your listing is replaced with a marker before it is sent, and each report is capped at 30 KB. We keep failure notes for 90 days. You can turn this off under Settings, Help, “Send the form’s layout with failure reports”; the short failure note itself is still sent.

Pro trial

When you start the free Pro trial, we store the email you enter with your browser's random ID and the trial dates. We use it to send three trial emails (a welcome, a reminder and a note when the trial ends), each with a link to unsubscribe, and to allow one trial per email.

To allow one trial per marketplace account, the extension also sends a one-way scrambled identifier for each marketplace account you're signed in to. It can't be turned back into your username or account ID, and we use it only to prevent repeat trials.

Email updates and support

If you give us your email in the extension, we store it with your browser's random ID and first send a link to confirm it. We use it only to send occasional product updates and fixes, and, if you leave “email me when an item sells” ticked, a sale alert. For a sale alert the extension sends us the sold item's title (up to 120 characters) and the marketplace it sold on; we use them only to write that one email and don't store them. Sale alerts are capped at 25 a day and each has a link to stop them. Every email has a way to unsubscribe, or you can write to us to be removed. When you send a problem report or idea, we store your message, the optional email, your browser's random ID, your license key if you have Pro, and the technical details you chose to include, so we can reply and fix the problem.

What our license service stores

For each purchase we store the license key, the Paddle transaction ID, the Paddle customer ID, the Paddle subscription ID and its status, the IDs of browsers where the key is active, when the license was created, and the daily usage counts described above. We use this only to deliver and verify your license. The service runs on Cloudflare, which may keep short-lived request logs, including IP addresses, for security and reliability.

Payments

Paddle is our merchant of record. Paddle collects your name, email, billing details and payment information to process your order, under Paddle's privacy policy. We never see your card details.

Cookies and analytics

This website doesn't use analytics or tracking cookies. The checkout on /buy loads Paddle's checkout, which may set cookies needed to process payment.

Your rights

You can ask us to show you or delete the data linked to your purchase, your email or your browser's ID. Deleting license data deactivates your license. Email support@octoresell.com.
