What we keep, and what we never see

The names, links, budgets and ad exports you put into our tools stay in your browser. We never receive them. We keep only what you choose to send us, and a count of which buttons get used.

What stays on your device

Everything you type, paste or drop into a tool: campaign names, UTM links, naming conventions, budgets, dates, spend, revenue and ad export files. The work happens in your browser, and nothing you enter is sent to us, apart from the one opt-in below.

To save you retyping, the tools keep your last inputs and settings (such as light or dark mode) in your browser's local storage. That copy stays on your device. To remove it, clear this site's data in your browser settings.

The Chrome extension

The Meta Ads Pre-Launch Checker extension reads the Meta Ads Manager page you have open (campaign, ad set and ad names, the link and its tags, locations and excluded locations, age, gender, budget and dates, and any errors Meta itself shows) and checks it inside your browser. It makes no network requests and asks for no permissions beyond running on Ads Manager pages and using the extension's own storage. The "How to fix" links open a WeekendProof page only when you click one, and they carry only the page address, never anything from your draft.

If you paste a campaign setup sheet into the extension to compare it with what you built, the sheet and the results of each comparison (the QC log) are kept in the extension's storage on your own device, so they are still there when you open the next campaign, ad set or ad. Click "Remove" in the panel to delete them. They are never sent to WeekendProof or anyone else. "Copy QC log" puts the log on your clipboard, and it goes only where you paste it.

What we keep

• Early-access signups. Your email, the date, and the poll answer and note if you add them. We use your email only to tell you about early access and our tools.
• Poll answers without an email. The answer you picked and the date, added to a daily total, plus the note if you write one.
• Button counts. When you use a tool, the page sends the name of the action (for example "check links") and we add one to that day's total. On the pacing calculator this also covers which field you moved a column to, and the reason if you tap "Something look wrong?". No IP address, no cookie and nothing you typed.
• Column names you choose to send. On the budget pacing calculator, "Send us the column names" shows you a preview first and sends nothing until you press Send. It sends each column's heading, the field we matched it to, and up to 3 cell formats with every digit turned into 9 and every word into "aaa" (so "₹1,234.50" becomes "₹9,999.99"). Campaign names, amounts and dates are never sent. We use it to read more export layouts correctly.
• Visit stats. Cloudflare Web Analytics counts page views, the site you came from, your browser type and country. Cloudflare says it uses no cookies and does not follow you across sites.
• Emails you send us. The "Wrong result? Tell us" button opens your own email app with the one link in it. Nothing is sent unless you press Send.

Who else is involved

Cloudflare hosts the site and stores the signups and counts above. We don't sell or share your email with anyone. Our fonts are served from our own site.

Your choices

Email hello@weekendproof.com to see or delete your signup, or to stop hearing from us. We keep your email until you ask us to delete it or early access ends.

Changes

If we add sign-in, payments or anything that stores more, we will update this page before it goes live.
