Online banking,
for all your data.

Your data already earns money — for everyone except you.
Tesco knows your dinners. Boots knows your headaches. Brokers you’ve never heard of sell both. That’s the unfair trade at the bottom of the modern economy: value flows out of your kitchen and never comes back.
Millions of people are misled and manipulated through data they gave away. Our members control their data — so they control their consumer decisions.
Your data account, working for you.
Standing orders for your data
Send data requests to the brands that store information on you — under UK GDPR, from your account. We send them, track the statutory clock, and file what comes back.
- Boots — day 12 of 30, on the clock
- Broker objection delivered — awaiting reply
- July Tesco statement filed to your account
Hedge yourself against inflation
Curious how your own consumer data can hedge you against inflation? Cut through the marketing and see what the best deal really is — priced from your own receipts, not an advert.
Keep your family’s data safe
Breach scans across the email addresses and phone numbers in your household — run a scan any time and see every breach that includes them.

Representative sample — not real member data
We take care of the techy bits. You keep control of the decisions.
- Keep it private — sharing is opt-in, always.
- Choose exactly what each partner sees.
- Delete any file, any time — it’s yours.
Why connect more sources?
Every source you connect does two things at once: it increases the union’s bargaining power with brands, and it sharpens your own picture — spending, health signals, and who’s had access to your details.
More sources → stronger position, sharper insights.
