By accessing or using AdCheckLab (including all tools, documentation, guides, and downloadable templates), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use our services.
AdCheckLab provides client side utility applications (Safe Zone Checker, HTML5 Banner Validator, clickTag Generator, Aspect Ratio Calculator, and PNG Mask Generator). All file operations occur strictly within your web browser using HTML5 Web APIs. We do not transmit, copy, or store your creative files on any external servers. There is no exception: the Pro features, Auto Fix included, run in your browser as well. When you are signed in, your account keeps the names and results of your checks, never the files (see section 6).
All creative assets, videos, images, ZIP files, and HTML snippets processed in your browser remain your exclusive intellectual property. AdCheckLab claims no ownership or rights over any content you check using our tools.
The AdCheckLab website, source code, visual design, custom safe zone coordinates algorithms, branding, and technical guides are the intellectual property of Filip Đorđević and protected under applicable copyright laws.
The tools and guides provided on AdCheckLab are offered on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind. While we rigorously test all safe zone margins and IAB validator rules against current publisher documentation (TikTok, Meta, YouTube, Google Ads, CM360), third party platforms may update their user interfaces or ad trafficking policies at any time without prior notice.
In no event shall AdCheckLab or its creator be liable for any indirect, consequential, or punitive damages resulting from your use of the tools, ad rejections by third party DSPs, or campaign distribution outcomes.
AdCheckLab Pro is an optional paid subscription that unlocks additional features. Every tool that is free today stays free, and Pro does not remove or limit any of them.
Payment. Pro is sold through Dodo Payments, which acts as the merchant of record. Dodo Payments processes the payment, issues the invoice and collects any sales tax or VAT that applies, and its own terms apply to the purchase. We never receive or store your card details.
Renewal and cancellation. The subscription renews automatically each month or each year until you cancel. You can cancel at any time with Manage subscription on your account page, which opens the Dodo Payments customer portal. Pro stays active until the end of the period you have already paid for and is not renewed after that. You can also switch between the monthly and the yearly plan in the portal. If a renewal payment fails, Pro stays on for 7 more days while the payment is retried, then pauses until the card is updated. A full refund or a chargeback ends Pro at once and cancels the subscription. Founder price: if you subscribe while Pro costs 9 USD a month or 79 USD a year, you keep that price for as long as your subscription stays active, even if the price for new subscribers rises later. If you cancel and subscribe again, the price at that time applies. Any other change to the price of your subscription is announced before it applies, and you can cancel first.
Refunds. If Pro is not for you, ask within 14 days of your first payment and that payment is refunded in full. Dodo Payments, as the merchant of record, processes the refund to your original payment method, and Pro ends when the refund is made.
Your account. Pro belongs to an account, which you sign in to with Google or with a link sent to your email. An account is for you or your organisation. Please do not publish your access or resell it; an account used to abuse the service may be suspended. You can delete your account at any time on the account page, once any active subscription is cancelled.
History and workspace. Your account keeps a history of your checks (names, sizes, dimensions and results, never the files) and your workspace (brand kits, naming convention, default rules). Free keeps 30 days of history and one brand kit. Pro keeps the history until you delete it, exports it as CSV and keeps up to 20 brand kits. You can switch the history off and delete it on the account page at any time. It is a convenience, not an archive: keep your own records of what you delivered.
Status check. While you are signed in, your browser asks AdCheckLab at most once an hour whether your subscription is active. No files are sent. If the check cannot be completed, Pro keeps working for up to 14 days after the last successful check. When a subscription ends, the Pro features lock again; your account and every free tool stay.
Auto Fix. Auto Fix is a Pro feature, not a service. It changes only the technical items listed on the Auto Fix page, inside your browser, and checks the result with the AdCheckLab validator. Passing the validator is not a promise that a platform will approve the ad, because platforms also review content and policy. Keep a copy of your original files.
