Privacy policy

Last updated 17 October 2026

PostHonk schedules and publishes your LinkedIn posts. We keep only what we need to do that, we never sell your data, and you can delete everything at any time. Murfin Ltd runs PostHonk from the United Kingdom and is the data controller for the information below.

What we collect

  • Your account: your email address, and your name and profile photo if you sign in with LinkedIn.
  • Your LinkedIn connection: the access token LinkedIn gives us when you approve PostHonk, stored encrypted, and your LinkedIn member id. We use it only to publish the posts you queue and to show whose profile they go to.
  • Your posts: the text, images and videos you queue, your posting schedule and your timezone. Videos are kept in private storage until their post goes out, then deleted. A video you remove, or one from a post you delete, is deleted within a day.
  • Billing: your plan and its status. Card details go straight to Stripe and never touch our servers.
  • Connected AI assistants: if you connect Claude or ChatGPT, which app you connected and when it was last used.
  • Setup links: if you ask us to email you a setup link from our homepage, your email address, when you asked, and where your visit came from (for example an ad, a link from another site, and your country). It isn't an account and doesn't sign you up to anything: we send that email, plus one reminder two days later if you haven't opened it or signed up, and note whether you later open it, sign up or start a plan. Both emails have a link to stop them.
  • Usage: anonymous page views and button clicks, and how many times you used Polish writing today. For the homepage demo we keep a scrambled (hashed) version of your IP address for a day to apply the free limit.

How we use it

  • To run your account: sign you in, schedule your posts and publish them to LinkedIn at the times shown.
  • To bill you for your plan through Stripe.
  • To email you about your account: sign-in links, your trial ending, and reminders when your queue runs low. You can turn reminders off in Settings, and every reminder has an unsubscribe link. Before you start a plan we may send up to three short emails about the free trial.
  • To keep PostHonk working and fair, for example the daily limits on Polish writing.

We don't use your posts to train AI models, we don't read them unless you ask us for help, and we never post anything you didn't queue.

When you connect Claude or ChatGPT

Connecting an AI assistant lets it add, list, edit and remove posts in your queue when you ask it to. It only sees your queue while you're using it, through the permission you approved. What you type into Claude or ChatGPT is handled by Anthropic or OpenAI under their own privacy policies, not ours. You can disconnect an assistant at any time on the Apps page in PostHonk, or in the assistant's own settings.

Who we share it with

We use a small number of providers to run PostHonk. Each gets only what it needs:

  • LinkedIn, to sign you in and publish your posts.
  • Stripe, for payments.
  • Resend, to send our emails.
  • Groq, which runs Polish writing. The text you choose to polish is sent to it and not kept for training.
  • Vercel and Supabase, which host the site, the database and videos waiting to be posted.
  • Umami, for cookie-free visitor statistics, and the Meta pixel, which tells us when an ad led to a sign-up.

Some of these providers are in the United States. Where your data leaves the UK, it's protected by the providers' standard data protection terms. We don't sell or rent your information to anyone.

Cookies

We use one essential cookie to keep you signed in. If you open a setup link we've emailed you, a cookie remembers that for 30 days so we can tell whether you signed up. The Meta pixel sets its own cookie on our website to measure our ads. Umami doesn't use cookies.

How long we keep it

We keep your account for as long as you have it. Posts are removed from your queue once they're published or you delete them. For published posts we keep only when each went out and its LinkedIn link, not the text. Sign-in links expire after 15 minutes. If you asked for a setup link and never signed up, your email address is deleted after 180 days, and you can ask us to delete it sooner. If you delete your account, everything above is deleted straight away, apart from billing records Stripe must keep by law.

Your rights

You can see and change your details in Settings, and delete your account there at any time. Under UK and EU data protection law you can also ask us for a copy of your data, or ask us to correct, restrict or delete it. Email hello@posthonk.com and we'll reply within 30 days. If you're unhappy with how we handle your data, you can complain to the Information Commissioner's Office (ico.org.uk).

Changes

If we change this policy in a way that matters, we'll email you before it takes effect. See also our terms.
