Privacy notice
Version 2.2 · 19 August 2026 · Tuesday app and website
This notice explains what we do with your information. It forms part of our terms of use — read them together. Where the two overlap, this notice governs anything to do with your personal data.
01Who we are
Tuesday is made and operated by Active AI Ltd, registered in England and Wales (company number 16499926), registered office The Rockery, Shap, Cumbria, CA10 3LY.
For the Tuesday app, Active AI Ltd is the data controller. We decide what is collected and what it is used for, and we are answerable to you for it. We are registered with the Information Commissioner’s Office under ZB911341.
Privacy contact: holly@weareactiveai.com
02Information we collect
What you give us
Account details — name, email address, password, and any profile details you add.
Activity you record — sessions you log, including type, duration, distance, timing, and any notes or effort ratings.
Crews and challenges — the crews you join, challenges you enter, and check-ins you make.
Anything you send us — emails, feedback, bug reports, survey answers, reports about other users.
What we collect automatically
App usage — screens opened, features used, and when.
Technical information — device model, OS and app version, approximate region, crash and diagnostic logs.
Location — only when you check in to a location-based challenge, and only at that moment.
What your connected device or service sends us
Activity data from the wearable device or fitness service you link to Tuesday. Tuesday needs a connection to work. The app tells you which devices and services are supported.
What we generate
Your momentum score and related indicators, produced automatically from the above.
03Health and fitness information
Information about your physical activity can reveal things about your health. Under UK and EU law that makes it special category data, which gets stronger protection.
Special category data needs two things — a general legal basis, and a separate condition for the health element. We rely on:
Performance of our contract with you (Article 6(1)(b)) for running your account and producing your score. That is the service you signed up for.
Your explicit consent (Article 9(2)(a)) for the health element. We ask for it separately and clearly in the app, before any activity data is collected.
Consent is the only condition in the law that fits an app like this one. If you withdraw it we can no longer process your activity data, and Tuesday cannot work without that — we will help you close your account and delete your data. Withdrawing doesn’t affect anything we did lawfully beforehand.
The same applies to using your activity data to develop and test our scoring model. Tuesday is built for that purpose, so it is not something you can switch off and carry on using the app. Section 6 sets out what it involves.
Separately from those two, these are genuinely optional and refusing any of them changes nothing else: local leaderboards, partner content, and marketing emails.
04Why we use it, and our legal basis
Core — needed to provide Tuesday
| Purpose | Legal basis | Health-data condition |
|---|---|---|
| Your account, the app, your momentum score and coaching | Performance of a contract | Explicit consent |
| Crews, fixtures and challenges you have joined | Performance of a contract | Explicit consent |
| Developing and testing our scoring model | Performance of a contract | Explicit consent |
| Fixing bugs, security, preventing misuse, handling reports | Legitimate interests | Substantial public interest |
| Meeting legal obligations | Legal obligation | As applicable |
Optional — refuse these and Tuesday works normally
| Purpose | Legal basis | Health-data condition |
|---|---|---|
| Your first name and score on a local leaderboard | Consent | Explicit consent |
| Deciding when to show you partner content | Consent | Explicit consent |
| Emails about the app | Consent | — |
Where we rely on legitimate interests, the interest is keeping Tuesday working and safe for everyone using it. We have weighed that against your rights and think it is a fair balance. You can object — see section 10.
We do not sell your personal data, and we do not share identifiable information with brands or advertisers.
05Your momentum score
Tuesday produces an automated score from your activity and app usage. It is shown to you, and it also determines what the app shows you next — coaching, a challenge, or content from a partner organisation. This is automated processing and it involves profiling.
It has no legal effect on you and we do not consider it to have any similarly significant effect. We do not use it for decisions about employment, credit, insurance, healthcare or access to any service. It affects what you see in a fitness app.
The methodology is proprietary and we do not publish the weightings. What we will always tell you is which categories of information feed it (section 2), what it is used for (section 4), and the general logic — it reflects patterns across your recent activity and app use, rather than any single session.
You can ask a person to review anything the score has driven, tell us what you think, and challenge the outcome. Email holly@weareactiveai.com. You can also object to the scoring entirely, in which case we stop generating a score for you.
06Improving our scoring model
Active AI Ltd licenses the technology behind Tuesday to other organisations, such as sports clubs, sports brands, governing bodies of sport, and operators who use it in their own apps. Activity data from Tuesday, including data from your connected device or service, helps us develop, test and validate that model.
We use it in aggregated or pseudonymised form wherever we can. We do not pass your identifiable personal data to those organisations, and they do not get access to your account.
Pseudonymised data is still your personal data in law, and all your rights still apply to it, including deletion. Only genuinely anonymised data — which nobody can link back to you — falls outside that, and we do not treat the two as the same thing.
This is not something you can turn off and carry on using Tuesday — developing and testing the score is what the app is for. If you would rather your data was not used this way, we will help you close your account and delete your data.
07Connected devices and services
Tuesday needs a connected wearable device or fitness service to work. We receive activity data from it and show it to you alongside what you record directly.
Data from your connected device or service feeds your momentum score, and we use it to develop, test and validate our scoring model. Tuesday is a test product built for that purpose — see section 6.
You can disconnect at any time, in Tuesday or from the other service. When you do, we delete the data we received from it. Because Tuesday needs a connection to work, you will need to connect another device or service to carry on using it, and we will help you close your account if you would rather not.
The provider of a connected service is a separate data controller for what happens on their own platform. Their privacy policy applies there, not this one.
08Who we share information with
| Provider | What they do |
|---|---|
| Fly.io | Hosting for the Tuesday backend service |
| Supabase | Database — your account details and the sessions you record |
| Netlify | Hosting for this website |
| MailerLite and MailerSend | Account and product emails |
| Umami | Website analytics — no cookies, no tracking across sites |
| Apple and Google | App distribution |
Each of these acts on our instructions under a written contract, except Apple and Google, who act as controllers in their own right for parts of what they do.
Other members of your crew see the sessions you contribute to a fixture, including any notes attached to them. People near you may see your first name and score on a local leaderboard. You control both under Settings → Privacy.
We may also share information where legally required, or in connection with a sale or reorganisation of our business — in which case we would tell you and this notice would continue to apply.
09Where it is held, and how long we keep it
Your information is stored in London. Where a provider processes it outside the UK or EEA we put appropriate safeguards in place, normally the UK International Data Transfer Addendum or the EU Standard Contractual Clauses. Ask us and we’ll tell you which applies where.
| Information | Retention |
|---|---|
| Account and activity data | While your account is open, then deleted within 30 days of closure |
| Data used to develop our model | Deleted with your account, unless genuinely anonymised |
| Data from a connected service | Deleted when you disconnect, or with your account |
| Feedback and support emails | 12 months |
| Reports about other users, and what we did about them | 24 months |
| Marketing contact details | Until you unsubscribe |
| Technical and security logs | 12 months |
Data that has been genuinely anonymised no longer identifies you, is no longer personal data, and is not deleted. Pseudonymised data is deleted with the rest.
10Your rights
You have the right to access your data, correct it, erase it, restrict or object to how we use it including the scoring, receive it in a portable format, withdraw consent, ask for human review of automated decisions, and complain to a supervisory authority.
Email holly@weareactiveai.com. We respond within one month and there is normally no charge. If a request is unusually complex we may extend that by up to two further months, and we’ll tell you why within the first month.
You can delete your account and everything in it from within the app, under Settings → Account. You don’t need to email us to do it.
11Withdrawing consent
Under Settings → Privacy you can withdraw consent separately for local leaderboards, for partner content, and for marketing emails. It isn’t all-or-nothing, and refusing one doesn’t affect the others.
Two things cannot be refused while you carry on using Tuesday: the health-data element of scoring, and using your activity data to develop and test the model. Section 3 explains why. If either is a problem, we’ll help you close your account and delete your data.
12Cookies
This website sets no cookies. There is no advertising and no tracking pixels — nothing is stored on, or read from, your device. That is why you have never been asked to accept anything here: there is nothing stored on your device to consent to.
If we measure how this site is used, we use Umami. It is cookieless: it stores nothing on your device, doesn’t follow you between websites, and doesn’t build a profile of you. It shows us page views and rough visitor numbers. It can’t identify you, and we can’t link it to your Tuesday account.
The one third party this site contacts is Google’s font service. The fonts you are reading are fetched from Google’s servers, which means your IP address reaches Google when a page loads. Google’s own privacy policy governs what they do with it.
The Tuesday app does not use cookies. What it collects and why is set out in sections 2 and 4.
13Age limit
Tuesday is for people aged 18 and over. You confirm your age when you create an account, and we may ask you to verify it. We don’t knowingly collect information from anyone younger. If you believe someone under 18 has given us their information, contact us and we’ll delete it.
14Changes
If we make a material change we’ll tell you in the app or by email, and update the version and date above, before it takes effect. If a change means we need a new consent from you, we’ll ask for it rather than assume it.
15Contact and complaints
