Free does the job.
Pro removes the ceiling.
Cataloguing what a page loaded, listening to it, searching it and exporting it in the format the page served are free, with no cap and no account. Pro covers the part that costs real compute: converting to MP3 and WAV, in bulk.

What the paid plan actually changes.
Four rows differ. Everything else that makes the panel useful is on the free plan, permanently.

The offer appears where the limit is.
There is no interstitial on install, no trial countdown, and no card asked for up front. When you spend the third free MP3 conversion of the day, the dialog you are already looking at says so and offers Pro. Decline it and the free plan keeps working exactly as it did.

Money questions, answered plainly.
Who actually charges my card?
Paddle, acting as merchant of record. They collect the payment, handle local taxes and appear on your statement. Card details are entered on their checkout and never pass through this site or the extension — we receive only your email address, the subscription status and the plan.
How do I cancel?
Open the extension's settings, sign in, and use Manage subscription. It takes one click and no email to anybody. You keep Pro until the end of the period you have already paid for, and then the account drops back to Free — nothing you exported is affected.
Do you offer refunds?
Yes. Write to contato@sericell.com.br within 14 days of a charge and we will refund it in full, no reason required. After that window, refunds are handled case by case — if something is broken on our side, you get your money back. The full terms are in our Refund Policy.
What happens when a renewal fails?
Paddle retries the charge for a few days. Pro stays active during the retries, and you get an email if it ultimately fails. If it does, the account returns to Free and you can resubscribe whenever you like — nothing is deleted.
Is there a team or volume plan?
Not yet. Pro is licensed per person, and one account signs in to the extension on the machines you use. If you need seats for a team, write to contato@sericell.com.br and tell us how many.
Do I need an account to use the free plan?
No. The free plan needs no sign-up, no email address and no card. An account only exists so that a Pro subscription can follow you between machines.
Can I switch between monthly and yearly?
Yes, from Manage subscription inside the extension. The change is prorated against what you have already paid.
What are the terms of use?
Audio Catcher is for collecting audio you own, have licensed, or are otherwise authorised to use. It does not decrypt DRM-protected content and does not bypass authentication or paywalls. Accounts used to infringe copyright, to breach a site's terms of service, or to circumvent technical protection measures are terminated without a refund. The full text is in our Terms of Service, and the summary is on the acceptable use section of the home page.

Install the extension and use it for as long as you like before deciding whether bulk conversion is worth two and a half dollars a month.
