Privacy
Last updated November 10, 2026
Kopitiam is a set of free document tools that run in your browser. This page says what we collect, why, and how to get it removed. No account is needed to use any tool.
The short version
- Your files stay on your device. PDFs, images and documents are opened, edited and saved inside your browser. They are not uploaded to us.
- Email is optional. After a download we may ask if you want one PDF tip a week. If you say yes, we keep your email for that and nothing else.
- Analytics only if you accept. If you choose “Essential only”, the analytics tool never starts.
- We do not sell your data, and we never share your email with advertisers.
Your files
Every tool on the site works on your device: the PDF editor, merge, split, extract, compress, rotate, redact, watermark, page numbers and the converters. The file is read into your browser’s memory, changed there, and saved back to your device as a download. We never receive the file, its name or its contents.
If we ever add a tool that needs a server to read your file, that tool’s page will tell you before you use it.
Email tips (optional)
After you download a file, a small card asks: “Get one PDF tip a week?”. You can ignore it or press “No thanks”. It never blocks a download.
If you enter your email and press “Send me tips”, we store:
- your email address,
- the time you agreed, and the exact words the card showed you,
- which tool you were using when you agreed (for example “merge”).
We use this only to send you tips and short product news, at most one email a week. It is stored in our database at Supabase, which we use as our data processor. Your email is not added to analytics and is never given to advertisers.
Every email has a one-click unsubscribe link. To have your email deleted completely, write to [email protected] and we will remove it.
To keep bots out, the form has a hidden field that people never see. We may also use Cloudflare Turnstile, a check that usually runs without you doing anything. It only loads when the email card appears.
Mobile app waitlist (optional)
If you join the waitlist on our app page, we store your email, which phone you said you’d use (iPhone, Android or either), whether you asked for an early test invite, the time you joined and the exact words the form showed you. If you arrived from a link with a short label (like ?ref=peerpush), we keep that label so we know which post brought people in. We don’t keep the full address you came from.
We use this only to email you when the app is out, plus one test invite if you asked for it. It’s a separate list from email tips: joining one doesn’t sign you up for the other. It’s stored at Supabase, like tips, and every email has a one-click unsubscribe. To have it deleted, write to [email protected].
Analytics (only if you accept)
If you press “Accept” on the cookie banner, we use PostHog to see how the site is used: which pages are viewed, which tools are opened, whether a download finished, errors the site hit, and basic device details such as browser, screen size and rough location from your IP address. It never sees your files or what is in them, and it is not given your email.
If you press “Essential only”, PostHog does not load at all. To change your mind, clear this site’s data in your browser and the banner will ask again.
Ads
Kopitiam is free because of ads from our partner Slate Ads. To show an ad, your browser asks Slate for one and tells it which ad space it is for, plus the random ID in the table below so the same ad is not repeated too often. Slate can also see your IP address and country, as any website you load can. Slate never sees your files or your email.
Other services the site loads
- Google Fonts. The site’s typefaces load from Google, which receives your IP address and browser details when they do.
- Cloudflare. Our hosting runs behind Cloudflare, which may set a short-lived security cookie (
__cf_bm) to tell people from bots.
What is saved in your browser
These stay on your device. Clearing this site’s data in your browser removes them.
| Name | What it is for |
|---|---|
kopitiam.consent | Your cookie choice (Accept or Essential only). |
kopitiam.theme | Light or dark theme. |
kopitiam.optin | Whether you said yes or "No thanks" to email tips, so we do not ask again. It does not hold your email. |
kopitiam.waitlist | That you joined the app waitlist and which phone you picked, so the page says "You’re on the list". It does not hold your email. |
kopitiam.iid | A random ID used by our ad partner to avoid showing you the same ad too often. It is not linked to your name or email. |
kopitiam.tour.seen, kopitiam.thumbs.* | Whether you have seen the editor tour, and the page-sidebar size. |
kopitiam.entitlement | Whether ads are switched off on this browser. |
| Design editor autosave | Your design, saved on this device so a closed tab does not lose your work. It never leaves your browser. |
Your choices and rights
You can ask us what we hold about you, ask us to correct it or delete it, and withdraw consent at any time. Unsubscribing from tips or choosing “Essential only” never changes what the tools can do. Write to [email protected] and we will reply within 21 days, the time Malaysia’s Personal Data Protection Act allows.
Changes
If we change what we collect, we will update this page and the date at the top first. For more about how Kopitiam stays free, see About.
