Privacy policy
Last updated: 15 November 2026
Merch Ads Pilot is a Chrome extension for Merch on Demand sellers. It is built so that your business data stays with you. This page says exactly what it reads, where that is kept, and what is ever sent anywhere.
The short version
- Your sales, royalties, ads, products and settings are read from Amazon, with your own login, and kept in your browser on your computer.
- They are never sent to us or to anyone else. We have no server that receives them.
- The only thing that ever leaves your computer for us is a licence check: your licence key (if you have one) and a one-way code made from your Merch account ID.
What the extension reads
Only from Amazon, in your own Chrome, while you are signed in:
- From Merch on Demand: your sales and royalties per design and day, your list of products, your account ID and your current US royalty group.
- From Amazon Ads: your campaigns, ad groups, ads, keywords and targets, and their daily numbers.
- From Amazon product pages you open or choose to track: price, rank, rating and reviews.
Where it is kept
In your browser's own storage on your computer (IndexedDB and Chrome's extension storage). Removing the extension deletes it. You can export it to a file for your own backup from Settings.
Two small values are also kept in Chrome's synced extension storage, which Chrome ties to your Google account when Chrome sync is on: the date your trial started and your licence key. This lets your key come back by itself if you reinstall.
What is sent, and to whom
| To | What | Why |
|---|---|---|
| Amazon | The requests Amazon's own pages make, with your login | To read your data, and to make the changes you approve |
| merchadspilot.com | A one-way code (SHA-256 hash) of your Merch account ID | To remember when your free trial started, so it is one trial per Merch account |
| Lemon Squeezy (our payment provider) | Your licence key and the same one-way code | To check, about once a day, that your Pro subscription is active |
The one-way code cannot be turned back into your Merch account ID. No sales, royalties, ad numbers, product names, campaign names, names or email addresses are sent by the extension.
Buying Pro
Payments are handled by Lemon Squeezy, which acts as the seller of record. When you buy, you give your name, email and payment details to Lemon Squeezy, not to the extension. Their privacy policy applies: lemonsqueezy.com/privacy. We receive your email and order details from them to provide support and your licence.
This website
This website uses no analytics, no tracking cookies and no advertising. Our host, Cloudflare, keeps standard technical logs (such as IP addresses) for security, under its own privacy policy.
Chrome Web Store: limited use
The use of information received from Amazon and Google APIs follows the Chrome Web Store User Data Policy, including its Limited Use requirements. Data is used only to provide the extension's features to you. It is not sold, not used for advertising, not used to decide creditworthiness, and not transferred to anyone except as described above.
Your choices
- Delete all data: remove the extension, or remove an ad account in the extension's Accounts page.
- Delete your trial record: write to us and we delete the one-way code we keep.
- Questions: [email protected].
Changes
If this policy changes, the new version is posted here with a new date. If the extension ever needs to send anything new, it will say so in the extension first.
