Privacy notice

This notice covers the Slackwise waitlist only. It says what we collect when you join, why, and what your rights are.

Last updated: 11 November 2026

Who we are

Slackwise is a trading name of Jake Redrupp, a sole trader, who is the data controller for the waitlist. To ask us anything about your data, write to hello@slackwise.app.

What we collect

• The email address you type into the waitlist form.
• A short label saying where you signed up, such as landing.
• The date and time you signed up (UTC).
• A confirmation token, used only to check your address. We email you the token in a link, but we store only a scrambled copy (a hash) of it, never the token itself, and we remove that copy once you confirm.
• The date and time we issued the latest confirmation link (UTC). It is the first link when you sign up, and a later one if we send you a new link (see below).
• The date and time you confirmed (UTC), once you do.

Our code does not store your IP address, browser details or any tracking identifiers, and it does not write email addresses to logs. This page and the home page have no analytics and set no cookies.

Why we collect it

Only to email you about the Slackwise waitlist, and nothing else. We send two emails:

1. One confirmation email after you sign up, asking you to confirm your address. Until you confirm, we do not add you to the list. If you do not confirm within 7 days, we delete the address. Our deletion job runs once a day, so the address is deleted within about a day after those 7 days (at most roughly 8 days after the email). The 7 days run from the latest confirmation link we sent you.
2. One launch email to confirmed addresses, telling you when Slackwise is ready for early users.

If you sign up again with the same address before you have confirmed, and our latest link to you is more than an hour old, we send you a new link. The new link replaces the old one, which stops working. If the latest link is less than an hour old, we send nothing, so please wait and check your spam folder. If you have already confirmed, signing up again changes nothing and sends nothing.

We will not use the list for interviews, feedback requests, research, pricing surveys or other marketing, and we will not sell or share it.

Our legal basis

Consent, for those two emails only. You give it by submitting the form and then confirming your address from the confirmation email. You can withdraw it at any time (see below), and that does not affect anything we did before.

How long we keep it

We keep an unconfirmed address for 7 days from the latest confirmation link and then delete it, in the daily deletion job described above (within about a day after the 7 days). We keep a confirmed address only until we have sent the launch email, and then delete it within 30 days. If we have not sent the launch email within 6 months of the day you confirmed, we delete your address at that point. We delete it sooner if you ask.

Deleted addresses may remain for a short time elsewhere. Resend may keep a record of the emails it sends for up to 30 days (see below). Our database also keeps point-in-time backup history for up to 30 days, so a deleted address can remain in that history until it ages out.

Who handles your data

We store the waitlist in a Cloudflare D1 database. Cloudflare acts as our processor: it hosts the data and the site for us and only handles it on our instructions. Cloudflare may also process technical request data, such as IP addresses, to deliver and secure its network. That is Cloudflare's own handling, not something our code stores.

The waitlist database is stored in the EU (Cloudflare D1, EU jurisdiction), but the code that handles your sign-up can run on Cloudflare's network anywhere in the world, so your address may pass through servers outside the EU on its way to the database.

Cloudflare's data processing addendum covers its role as processor and its safeguards for transfers of personal data out of the UK. See its terms for details.

Resend (resend.com) sends our emails for us, and is also our processor. It receives your email address and the content of the confirmation email, and later the launch email, so that it can deliver them. Resend's data processing addendum sets out its role and duties, and it publishes a list of its own subprocessors and a privacy policy.

Resend's main processing takes place in the United States, so your address is transferred there. We have set Resend to send our email from its Ireland region, but that only affects where the mail is sent from: Resend says its account data, including email metadata and logs, is stored in the United States whichever region is chosen. Resend's addendum says transfers out of the UK and EEA are made under standard contractual clauses (with the UK Addendum for UK transfers), and that Resend complies with the EU-U.S. Data Privacy Framework and its UK Extension.

Resend may keep records of the emails it sends for a limited time. Its pricing page lists 30-day data retention.

Apart from Cloudflare and Resend, we do not use any other service for the waitlist at present.

Your rights

Under UK data protection law you can ask us to:

• tell you what we hold about you and give you a copy;
• delete your email address from the waitlist;
• correct it, or stop using it;
• and you can withdraw your consent at any time.

Write to hello@slackwise.app from the address you signed up with. We will reply within one month.

Complaints

If you are unhappy with how we have handled your data, please complain to us first at hello@slackwise.app. We will acknowledge your complaint within 30 days and tell you the outcome without undue delay. You can also complain to the UK Information Commissioner's Office (ICO) at ico.org.uk/make-a-complaint.
