This Privacy Policy explains how PostMock ("PostMock", "we", "us") handles information when you use postmock.com (the "Service"). We've written it in plain language. By using the Service you agree to this policy.
The conversations, names, images and other content you build with our generators are processed entirely in your browser. They are not uploaded to or stored on our servers, and we cannot see them. When you close the tab, that content is gone. Images you download are saved by your own browser to your device.
If you use the "Generate with AI" feature, the short text prompt you enter is sent to our AI provider (Groq) to generate a response. We send only the prompt text needed to produce the result; we do not attach your identity. We do not permanently store these prompts. The provider processes them under its own terms.
If you choose to import a profile by username, our server requests that account's public profile information (name, public profile photo, public verified status) from Instagram's public endpoints and returns it to your browser to populate the mockup. We may briefly cache a public profile result to reduce repeat requests. We only access information that is already public, and only when you explicitly request it. We are not affiliated with Instagram or Meta.
We may use privacy-respecting analytics to understand aggregate, anonymous usage — such as which pages are visited and from which country — so we can improve the Service. This data is not used to personally identify you.
We may display advertisements through third-party networks, including Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this and other websites.
The Service is not directed to children under 13 (or the minimum age in your country), and we do not knowingly collect their personal data.
Depending on where you live (for example under GDPR or CCPA), you may have rights to access, correct or delete personal data we hold about you. Because we store almost no personal data, there is usually nothing to retrieve — but you can contact us with any request.
We use reasonable technical measures to protect the limited data the Service processes. No method of transmission over the internet is 100% secure, but keeping content in your browser by design reduces risk.
We may update this policy as the Service evolves. We'll change the "Last updated" date above. Continued use means you accept the current version.

PostMock is a free browser-based generator for fake chat and phone screenshots. It renders a realistic mockup of a messaging app — WhatsApp, iMessage, Instagram DM, Snapchat, Discord, Telegram, Messenger, Tinder, Bumble, Hinge, ChatGPT, Claude — from text you type, and exports it as a high-resolution PNG. It is used for memes, parody, comedy content, social media posts, UI mockups, presentations and app-design previews.
Yes, and there is never a watermark on any export. Without an account you get 5 free PNG downloads, plus 3 more for each of up to 2 shares (11 in total). After that a free Google sign-in is required, and signed-in users have unlimited downloads. Video exports require sign-in from the first download. There is no paid tier and no subscription.
No install. PostMock runs entirely in the browser on desktop and mobile — there is no app to download and nothing to configure. Editing and preview happen client-side; the screenshot is rendered in your own browser rather than on a server. You can start typing and see the preview without an account.
Describe a scenario in plain language ("two friends arguing about pizza") and PostMock writes the whole conversation for you, in short, natural, realistic messages. It can also continue an existing conversation by writing the other person's next replies. Tweets can be generated the same way.
18 generators in total: 12 chat apps (iMessage, WhatsApp, Instagram DM, Snapchat, Messenger, Telegram, Discord, Tinder, Bumble, Hinge, ChatGPT and Claude), plus tweet/X posts, iPhone call and FaceTime screens, Instagram Stories, WhatsApp Status, and iPhone lock screens with notifications. It also has 80 ready-made scenario templates and 27 how-to guides. A separate tool downloads public Instagram reels and videos.
PostMock is built for parody, comedy, memes, content creation, mockups and design previews, and it says so on every page. Using a fabricated screenshot to deceive, defraud, impersonate a real person, harass someone, or manufacture evidence is wrong and in many places illegal — that is not what the tool is for and it is explicitly discouraged in the product. Creators should label parody content as parody.
Screenshots are rendered in your own browser rather than uploaded to a server. Signing in with Google is optional and is used to save your creations and lift the download limit. The privacy page states what is collected and why.
