Who we are
The TK Privilege app is provided by Tatiana Karelina Ltd, the company that runs the Tatiana Karelina salons. We are the data controller for the information described here. You can reach us at info@tatianakarelina.co.uk, on +44 (0) 20 3645 1761, or by post at the address above.
What the app is for
TK Privilege is for existing Tatiana Karelina clients. It shows your Privilege card, your TK Points and Tier Points, your Care Card, your recent visits and your next appointment, and it lets you refer a friend, share a review, ask for an appointment and keep your own details up to date.
What we collect
Your name, mobile number, email address, home address and postcode. Your birthday, day and month only, and your occupation, both of which are optional. Your preferred stylist, how you like your hair and how you prefer to be contacted. Your appointment history with us, what you have spent, your points balance and history, your Care Card, your tier, your referral code and the friends who have used it, and whether you have tapped through to leave a review. Your marketing choices. Basic technical information from your device, such as the app version and crash reports, so we can keep the app working.
We do not collect payment card details in the app, and we do not track you across other apps or websites.
Where it comes from
Most of it is already held in our salon system because you are a client of ours. You add to it or correct it yourself on Your Details. Your visits, spend and points come from your appointments and bills at the salon.
Why we use it, and our legal basis
To run your Privilege membership, show your card and points, and give you what the scheme promises. This is necessary to perform our agreement with you as a member.
To book and manage your appointments and to contact you about them. This is necessary to perform our agreement with you.
To keep the app secure, prevent fraud and fix faults. This is in our legitimate interests in running the app properly.
To send you marketing by email or text. This is done with your consent, and you can withdraw it at any time in the app or by telling the salon.
To meet our legal duties, for example keeping records for tax.
Signing in
You sign in with your mobile number and a one time code sent by text. The code is sent through our messaging provider, Twilio. If you choose to stay signed in, your phone keeps a secure sign in for 90 days.
Who we share it with
Supabase, which hosts our database. Twilio, which sends the sign in text. Expo and the app stores, which deliver the app and crash reports. Our salon booking system. None of them use your information for their own purposes, and all of them are bound to keep it secure.
When you choose to leave a review, you are taken to Google or Trustpilot and anything you post there is public and governed by their terms. When you share your referral code, you choose the app you send it in and what it says.
We never sell your information.
Where it is kept
Our database is hosted in London, so your client record, your appointments and your points are stored in the United Kingdom. Our messaging provider, Twilio, handles your mobile number on its own network outside the UK when it sends your sign in code. Where a provider processes information outside the UK, we rely on the UK approved safeguards for that transfer.
How long we keep it
We keep your client record while you are a client of the salon and for 6 years after your last visit, which covers our tax and accounting duties. Points and Care Card history are kept for as long as they can still be used, and points expire 24 months after they are earned. Crash reports are kept for up to 90 days.
Deleting your account
You can delete your TK Privilege account at any time in the app, on Your Details, by choosing Delete my account. You can also ask us to delete it by writing to info@tatianakarelina.co.uk from the email address on your account, or by calling us on +44 (0) 20 3645 1761.
Deleting your account removes your app sign in, your TK Points and Tier Points balance and history, your Care Card, your referral code and the record of reviews you have shared. Any unspent points end with the account and cannot be restored. This happens within 30 days of your request, and backups holding the same information are overwritten within a further 90 days.
It does not delete your client record at the salon. We keep your name, contact details and appointment and treatment history because we still need them to look after your hair safely and to meet our tax and accounting duties, as set out under How long we keep it above. To ask us to delete or correct that too, write to info@tatianakarelina.co.uk and we will do so unless the law requires us to keep it.
Your rights
You have the right to ask for a copy of the information we hold about you, to have it corrected or deleted, to object to or restrict how we use it, to withdraw consent to marketing, and to ask for your information in a portable form. Write to info@tatianakarelina.co.uk and we will answer within 1 month.
If you are unhappy with how we have handled your information you can complain to the Information Commissioner’s Office at ico.org.uk or on 0303 123 1113.
Children
TK Privilege is for salon clients aged 16 and over. We do not knowingly hold app accounts for anyone younger.
Changes
If we change this policy we will update this page and, where the change matters, tell you in the app.
