Premium

Columnproof Premium

The review itself is the free product and stays that way: profile both files, read every finding, commit every rename, dispose of everything, and take your checkpoint with you. Premium is the volume and the handoff, the parts that turn one review into something you send.

What Premium adds

Subscriptions renew automatically and can be cancelled at any time from the link in your receipt email. Access is recorded in this browser, not in an account: keep your access code and your receipt email. Already subscribed in another browser? Restore access.

What a purchase sends, and to whom

The application does not upload your review files, before or after a purchase. Files you export and deliberately share are under your control. Plan loading, checkout, access restoration and periodic entitlement checks use the network: the page loads RevenueCat's Web Billing code and Stripe's card fields, and your card details go directly to Stripe. RevenueCat records that an anonymous identifier holds a subscription; Stripe records the payment and your email address for the receipt. Neither of them receives a file name, a column name, a finding, or anything else from your review, because the workbench never sends it anywhere.

After a purchase this browser keeps one small record: whether the subscription is active, and when that was last confirmed. Automatic boot checks are limited to once every twelve hours while online; purchase and manual restoration may check sooner. Cached Premium access can work offline for up to thirty days since its last successful confirmation.

Refunds and support

Email socialreminderinfo@gmail.com within 14 days of a first purchase, or within 7 days of a renewal, and it will be refunded. Write from the address you paid with and include your access code. The full wording is in the refund policy.
