Privacy notice for callers: missed-call text line
The short version. You rang a business and nobody could answer. That business uses a missed-call text line run by TurboKast Ltd. It plays a short message, lets you leave a voicemail if you want to, sends you one text, and tells the business. We use your number and any message only to deal with the call you made. No marketing, nothing else.
Who is responsible for your details
The business you rang decides what happens to your details and is responsible for them (in law, the “controller”). Its name is in the message you heard and in the text you got. TurboKast Ltd (company number SC881077, 29 Commercial Street, Dundee, DD1 3DG) runs the text line for the business and handles your details only on the business’s instructions (in law, its “processor”). The business may also have its own privacy notice: ask it for a copy.
What we handle, and why
| What | Why |
|---|---|
| The number you rang from, and the time and length of the call | So the business knows who rang, and so we can text you |
| A voicemail, if you choose to speak after the tone (up to one minute) | So the business hears your message |
| An automatic typed-up version of the voicemail | So the business can read it quickly. It can contain anything you said |
| The text we send you, and your reply if you send one | To let you reply to the business, and for the business to answer you |
| A note that you replied STOP, or that we texted you in the last 12 hours | So we do not text you again. We keep these as a scrambled code, not your readable number |
The business will normally rely on its legitimate interest in dealing with the call you made to it. It is for the business to say what its basis is: ask it.
This is not marketing. The text is a reply to your call and says how to stop it. We send nothing promotional, and the business cannot add anything. We only text a UK mobile number that has just rung, and at most once every 12 hours.
How long we keep it
| What | How long |
|---|---|
| Voicemail recording | Deleted as soon as the typed-up version has reached the business. If something went wrong, kept for up to 7 days, then deleted |
| Typed-up voicemail | The company that types it up does not keep it once it has done the job. The business keeps it in its own phone or inbox as long as it chooses |
| Your number, the time of the call, the texts and your replies, in our phone provider’s log | 30 days, then deleted |
| “Do not text this number” note | Until the business stops using the service, then deleted within 30 days |
| “Texted in the last 12 hours” note | 12 hours |
Who else handles it
- Twilio (a US company) provides the phone number, takes the call, records the voicemail and sends the texts.
- Deepgram (a US company) types up the voicemail. We switch off its option to use recordings to improve its own models. It keeps nothing once the voicemail is typed up.
- Cloudflare (a US company) runs the service and keeps the short-lived notes above.
Because these are US companies, your details may be handled in the US. The transfers are covered by the safeguards the UK law requires: the UK-US Data Bridge (Twilio), or standard contract clauses with the UK Addendum (Deepgram and Cloudflare). We do not sell your details and nobody else sees them.
If you say something sensitive
A voicemail can include things like your health. We do nothing with it except pass the typed-up message to the business, but it will be in the recording and the typed-up message until they are deleted. You do not have to leave a voicemail: hang up instead, or leave only your name, your number and what it is about.
Your choices and rights
- Stop texts: reply STOP to the text. You will get no more from that business through this line.
- No voicemail: hang up before the tone.
- Your rights (to see your details, correct them, have them deleted, or object): ask the business you rang. If you ask us, we pass it to the business within 2 Working Days. Our log holds very little and not for long, so we can usually find your call only by your phone number.
- Contact us: [email protected], marked “Data protection”.
- Complain: to the Information Commissioner’s Office (ico.org.uk, 0303 123 1113). We would rather you told us or the business first, but you do not have to.
