Three doors. Pick one, or take your time.

Up to 5 devices on Pro Monthly or Yearly, and up to 10 on Founder Lifetime. A device is one Chrome install where you paste your license key. If a device sits unused for 60 days, its seat is released automatically.

One Chrome install on one machine. Chrome on your laptop and Chrome on your desktop count as two. Reinstalling Chrome on the same machine can register as a new device, in which case the older entry will roll off after 60 days, or you can free it yourself from the manage page.

You probably reached the device limit and the oldest seat dropped you. Visit www.shelf-extension.com/manage, enter the email tied to the license, and you will see every active device. Revoke the one you no longer use, then paste your license key on the laptop again.

Yes — open your Stripe customer portal (the link is also in every receipt email) and switch plans. Stripe prorates the remainder of your current cycle automatically.

Open the Stripe customer portal, enter the email you used at checkout, and Stripe will send a sign-in link. From there you can cancel in one click, change your payment method, or download invoices. The same link is included in every purchase email under "Manage your subscription". No password to remember, no account to create on our side.

You keep Pro through the end of the period you paid for, then revert to Free. The Free tier handles your library indefinitely — saves, exports, the daily loop — none of that requires Pro.

Forever. There is no v2 plan that resets the deal. All future Pro features land on Founder licenses at no additional cost. The cap (200 supporters) exists so the maker can promise this honestly, not to invent scarcity.

For subscriptions: within 14 days of purchase if you have not actively used the Pro features. For Founder Lifetime: within 14 days if the license key has not been activated on any device. After activation, refunds are case-by-case — email and we will talk.

Stripe processes the payment and the receipts. The invoice is issued by Shelf (the maker, as a registered Italian sole proprietor with P.IVA) — Italian VAT applies for EU consumers. Footer below has the legal details.

Visit /recover, enter the email you bought with, and we re-issue the key. The license is signed against your Stripe customer record, so as long as the purchase exists, the key can be re-emitted.

No. Enhanced Safe Browsing only marks an extension trusted after it has been on the Web Store long enough to build a track record. Shelf is new, so it has not earned that status yet — every new extension starts here regardless of how it behaves, and nothing was flagged. It clears on its own with time and continued policy compliance; there is no appeal or way to speed it up. What you can verify today instead of taking it on trust: the privacy policy lists every network call Shelf makes — free readers send nothing, Pro makes one signed license check a week — and the permission list Chrome shows on the store page is exactly what the extension can touch.
