Account data: name, email address, hashed password, and the IP address used at sign-up. We send transactional email only (verification, password reset, trial and billing notices, plan changes).
Links you create: the Amazon URL, ASIN, keywords, seller ID, coupon codes and any landing-page text you enter.
A browser cookie named uuid so guests can see the links they created without an account. When you sign up, links created under that cookie are attached to your account.
Payment: handled by Stripe. We never see or store your card number. We store your subscription id, plan, subscription status and billing dates, to start, renew, change and end your subscription.
What we collect from people who click your links (the visitor)
Time of the click, the country derived from the IP address, device type, operating system, browser, the referring page (host and path only, no query string) and the channel tag you put in the link (?c=).
The IP address is hashed before storage and is not kept in clear text. We use the hash only to de-duplicate repeated clicks and to filter bots.
If a visitor enters an email address on one of your coupon landing pages, that address is stored for you and is shown only to you. You are responsible for how you use it. Because you can export that list, the email is stored together with the visitor's IP address and browser user-agent string in clear text — unlike click statistics above, where the IP address is only ever stored as a hash.
A device check on coupon landing pages. To spot the same person claiming a code twice, the page reads six stable traits of the browser — screen resolution, colour depth, colour gamut, CPU architecture, platform and time zone — and turns them into a one-way hash inside the visitor's browser. Only that hash reaches us, and we salt and hash it again before storing it. We never receive the raw values. The check deliberately avoids canvas, audio and font probing. It uses FingerprintJS 5.2.0 (MIT licence), served from this site rather than a third-party CDN.
Analytics and third parties
The seller-facing site uses Google Analytics. Visitor-facing redirect pages do not.
We do not sell data. We share data only with Stripe (payments) and our hosting provider (infrastructure).
Your rights
Email [email protected] to export or delete your account and its links. Deleting your account deletes your links and their statistics.
2. Terms of service
What the service does: creates short links and Amazon "Super URLs", coupon landing pages and single-use code distribution, and reports click statistics. We do not guarantee any effect on Amazon search ranking or sales.
Your responsibility: you must comply with Amazon's terms and policies and with applicable law when you use links, coupon codes or collected emails. Do not use the service for spam, deceptive redirects or any content you have no right to promote.
Plans: Guests can create 5 links, each of which stops redirecting 30 days after it is created. Accounts without a subscription get the same limits. Subscriptions are priced by the number of active links you keep: 20 / 200 / 2000 links for $19.99 / $59.99 / $119.99 a month. Every plan includes all features and unlimited clicks. Active links are all links you own and have not deleted, including paused ones; links created before these plans launched keep redirecting and do not count. Limits and prices are listed on the pricing page and may change with notice on that page.
Free trial: each account can use one 7-day free trial, and a card is required to start it. Nothing is charged during the trial. When the trial ends, the monthly price of the plan you chose is charged to that card automatically, and the subscription then renews every month until you cancel. If you cancel before the trial ends, you are not charged. We email you when the trial starts, with the charge date and amount, and again 3 days before the first charge.
Billing: subscriptions are billed monthly in US dollars through Stripe and renew automatically until cancelled. Your plan starts once the payment service confirms your checkout; if it is not active within 10 minutes, email us and we will sort it out.
Changing plans: upgrades apply immediately. During the trial nothing extra is charged and the new price applies when the trial ends; on a paid subscription the prorated difference for the rest of the current period is charged right away, and the upgrade applies only if that payment succeeds. Downgrades: the lower price applies from your next billing date and the smaller limit applies as soon as you switch, so you first need to delete links until you are within it. Plans cannot be changed after you cancel.
When a subscription ends: after you cancel, your plan keeps working until the end of the trial or of the period you paid for. When it ends — including when a renewal payment has still not gone through by that point — links created on your plan stop redirecting and show a notice page, and you cannot create new links. If you never paid for a plan (for example, you cancelled during the free trial), your account instead goes back to the limits for accounts without a subscription described under Plans. A failed payment on its own does not cut your access: while there is still time left on the period you paid for, everything keeps working as Stripe retries the card. Nothing is deleted: your statistics stay available, and paused links redirect again as soon as you subscribe again.
Availability: we run the service with reasonable care but provide it "as is", without a guaranteed uptime. Bot clicks are filtered automatically and are excluded from your statistics; no filter is perfect.
Termination: we may suspend accounts used for abuse. You may delete your account at any time by email.
Amazon: amz.do is independent and is not affiliated with, endorsed by, or funded by Amazon.com, Inc.
3. Refunds & cancellation
Cancel any time from the plan card on your account page, or by emailing [email protected]. Cancelling stops all future charges; your plan keeps working until the end of the trial or of the period you already paid for.
Free trial: the 7-day free trial is how you try amz.do before paying. Cancel before it ends and you are never charged.
Payments: the first charge after the trial, monthly renewals and prorated upgrade charges are not refunded once taken, including when you downgrade or cancel partway through a period, except where required by law.
Charged in error: if we charged you by mistake, for example after you cancelled, email [email protected] and we will refund it. Refunds go back to the original card through Stripe, usually within 5–10 business days.
