LEGAL / PRIVACY POLICY
Privacy policy
LAST UPDATED: 08 OCTOBER 2026
1. Who we are
MISSIN is provided by MISSIN LIMITED (MISSIN, we, us), a company registered in Scotland, registered office 20 Arthur View Terrace, Danderhall, Dalkeith, EH22 1NT. For anything in this policy, email Sam@missin.co.uk.
2. Our two roles
- Controller, for our own customers. When you sign up for MISSIN, use the app or pay for a plan, we decide how your data is used. This policy covers that data.
- Processor, for merchants. When a merchant uses MISSIN to run forms, waitlists, discounts or attribution, we process their customers' data on the merchant's instructions, under our data processing agreement. The merchant is the controller, and its own privacy notice explains what it does. If you are one of a merchant's customers, contact the merchant first; we will help them answer.
3. What we collect about our customers
- Account and sign-in. Your name, email address and profile picture, and records of when you sign in. Our identity provider holds these; MISSIN keeps only your sign-in id, the workspaces you belong to and your role in each.
- Workspace. The workspace's name and settings, the people invited to it, and the API keys created in it. We store only a hash of each API key, never the key itself, and a daily count of the requests each key makes.
- Billing. Your plan, your usage and the billing contact. Card payments are taken by Stripe: MISSIN never sees or stores your card number.
- Connected accounts. When you connect a store or a tool, we keep the access credentials it gives us, encrypted, and the data MISSIN reads from it to do its job, such as the orders and discounts in a Shopify store.
- Support. What you send us when you email us.
- Errors. When the app hits an error, a report goes to our error monitoring. Names, contact details, addresses, IP addresses and free text are removed from it first.
4. What we process for merchants
On a merchant's behalf, as the data processing agreement describes:
- Orders. The order references, totals and customer id a merchant's store reports, and the customer's email address where it is needed to match an order. We do not read customers' names, addresses or phone numbers from Shopify.
- Form answers. What a customer answers on a merchant's form, including free text. To work out which touch-point earned an order, free-text answers are sent to an AI model provider after email addresses, links, phone numbers and long numbers are masked.
- Waitlist sign-ups. The email address, the page and campaign the sign-up came from, and proof of consent: the decision, when it was made, the wording shown, the browser's user agent and a keyed hash of the IP address. We never store the IP address itself.
- Visits. On a merchant's website, the MISSIN snippet records a visitor id, the pages visited, the referrer and campaign parameters. Advertising click ids are kept only when the website signals marketing consent.
- Partners' public posts. The public posts and handles of the people who post for a merchant, and of the accounts those posts tag or mention, so the merchant can see which posts earned orders. The merchant chooses whose posts are tracked and is responsible for the lawful basis, usually its legitimate interests; MISSIN collects them as its processor, under the data processing agreement. Details of accounts that are not a merchant's partners are deleted after 90 days without being seen again, and anyone can ask not to be collected.
5. Why we use our customers' data, and our lawful basis
| Purpose | Lawful basis |
|---|---|
| Creating your account, running your workspace and providing the service | Contract |
| Taking payment and keeping billing records | Contract, and our legal obligation to keep accounts |
| Keeping the service secure and preventing fraud and abuse | Legitimate interests |
| Fixing errors and improving the service | Legitimate interests |
| Answering your support requests | Contract, or legitimate interests if you are not yet a customer |
| Sending service emails: account, billing and alerts | Contract |
| Telling you about changes to the service or these documents | Contract |
We use each workspace's data only to provide the service to that workspace. We do not use it to improve Mend for other workspaces, we never sell it, and we never use it to train third-party AI models.
Today we send only service emails. If we start sending marketing emails, we will send them to existing customers only, under the UK soft opt-in, with an unsubscribe link in every one.
6. Where your data is processed
MISSIN's servers and database run in the EU, in Railway's europe-west4 region. Some of our providers process data outside the UK and the EEA. Each such transfer relies on the UK International Data Transfer Agreement or Addendum, the EU Standard Contractual Clauses, or the UK Extension to the EU–US Data Privacy Framework where the provider is certified. The mechanism for each provider is available on request.
7. Who we share it with
We do not sell personal data. We share it only with:
- the providers that run parts of the service for us: hosting, sign-in, email sending, payments and usage billing, error monitoring, bot checks on forms, AI classification of form answers, and collecting public posts. They are listed, with their location, on the sub-processor list;
- the stores and tools you connect yourself, when you tell MISSIN to send data to them;
- the members of your own workspace;
- authorities, when the law requires it.
8. How long we keep it
- Your account is kept while you use MISSIN. A sign-in account that no longer belongs to any workspace is not deleted automatically; we delete it when you ask.
- A deleted workspace is kept so it can be restored. We delete it within 30 days if you ask us in writing. This is done by hand today, not automatically.
- Billing records are kept for six years, as HMRC requires.
- Website visits are deleted after 13 months. Customer details captured with a form answer are removed after 13 months; the answer itself is kept as proof that a reward was earned.
- Waitlist sign-ups that are never confirmed are deleted 30 days after the last attempt. After a waitlist is released or archived, sign-ups without marketing consent are erased once the merchant's retention period has passed (180 days unless the merchant chose between 30 and 730). Sign-ups with marketing consent are kept until the person unsubscribes or asks to be erased.
- Customer data request exports are deleted after 30 days.
- A Shopify store's data is erased when Shopify tells us the store has uninstalled MISSIN.
9. Your rights
You can ask us to give you a copy of your data, correct it, delete it, limit how we use it, or send it to you in a portable format. You can object to a use based on our legitimate interests, and withdraw any consent you gave. To do any of these, email Sam@missin.co.uk. We answer within one month.
If you are a merchant's customer, ask the merchant: it controls your data, and we help it answer.
10. Cookies and browser storage
MISSIN does not use advertising or analytics cookies, and the MISSIN website, docs and app do not run analytics trackers.
- The MISSIN app keeps your sign-in in memory and a cookie,
sidebar_state, for seven days to remember whether the sidebar is open. It keeps preferences (theme, layout and unsaved drafts) in your browser's local storage. Our identity provider sets its own cookies on its sign-in page to keep you signed in. - The MISSIN website and docs set no cookies. They keep only your theme choice and dismissed announcements, in local storage.
- On merchants' websites, which we serve as processor: the MISSIN snippet
keeps a visitor id in local storage and in a first-party cookie,
missin_vid, for up to 400 days; a MISSIN form setsmissin_rsfor 24 hours to keep one answer session; and the form's bot check is run by Cloudflare Turnstile. The merchant is responsible for asking its visitors' consent where that is needed.
11. Security
Data is encrypted in transit, the credentials for the tools you connect are encrypted at rest, each workspace is kept apart from every other, and access is limited to the people who need it. More is on the trust center's security page.
12. Children
MISSIN is a service for businesses and is not meant for children.
13. Changes to this policy
We will update this policy when what we do changes. The date at the top of this page shows when it last changed, and we will email workspace owners about a change that affects them.
14. Contact and complaints
Email Sam@missin.co.uk, or write to us at 20 Arthur View Terrace, Danderhall, Dalkeith, EH22 1NT.
If you are unhappy with how we handle your data, you can complain to the Information Commissioner's Office, the UK data protection regulator, at ico.org.uk/make-a-complaint or on 0303 123 1113. We would like the chance to put it right first.
Sam, on behalf of MISSIN
