privacy policy
last updated: 1 august 2026
this policy explains what personal information certified random collects when you use blank, our autonomous ai trading advisor, how we use it, and the rights you have over it.
who we are
certified random is the publisher of blank and the data controller for the personal information described below. you can contact us at privacy@useblank.ai.
information we collect
- account information: your name, email address, postal address, and a securely stored password.
- billing information: a payment-card reference held by our payment processor. we never receive or store your full card number.
- your trading 212 api key: when you connect your trading 212 account, your api key (and secret, if applicable) is stored on our servers in encrypted form so you can connect it once and blank can use it from the desktop app you sign into to place trades on your account. we never share it with anyone outside our service and you can disconnect or remove it from your dashboard at any time.
- account activity: records of your plan purchases (£10 trading weeks and the £35 rolling-30-day subscription), commission charges, account credit, and events that affect your account (sign-ins, plan changes, payment failures).
- trade records: the fills your advisor places (ticker, side, quantity, price, and realised profit) are uploaded to your account. this is what powers the trade history in your dashboard and the calculation of the monthly 5% commission on realised profits.
- advisor chat: messages you exchange with the advisor sync through our servers so your conversation follows you between the desktop app, the iphone app, and the dashboard. we don't read them except where necessary to operate the service or investigate a fault you report.
- basic usage signals: anonymous app version and uptime pings used to keep the service healthy, plus error reports if blank crashes. these reports do not include your portfolio, trades, or personal files.
information we do not collect
- we do not collect your browsing activity outside blank.
- we do not track your location.
- we do not sell your data, share it with advertisers, or use your trades or chat for anything beyond operating the service described above.
how we use your information
- to operate your account and provide the service.
- to charge subscription and commission fees, and to prevent fraud.
- to send you essential service emails (sign-up confirmation, billing receipts, security alerts).
- to investigate bugs and improve the product.
- to comply with legal and regulatory obligations.
we send marketing emails only with your explicit consent and you can unsubscribe at any time.
who we share information with
we share the minimum information needed with carefully chosen service providers who help us run the service: a payment processor (for card transactions), an email provider (for transactional emails), and our hosting provider (for running the service itself). these providers are bound by contract to protect your data and use it only for the services they provide to us.
we never sell your personal information.
how long we keep your data
we keep your account information for as long as your account is open. after you close your account we keep limited records for up to six years to meet our accounting and legal obligations, then delete or anonymise them.
your rights
if you are in the uk or eu, you have rights under the uk gdpr and eu gdpr to access, correct, or delete the personal data we hold about you, to object to or restrict our processing, and to request a portable copy. similar rights apply in some other regions. to exercise any of these rights, email us at privacy@useblank.ai from the address on your account and we will respond within 30 days. you also have the right to lodge a complaint with your local data-protection authority.
cookies & tracking
this website uses strictly-necessary cookies only: your sign-in session and the stripe payment widget on the signup page. there is no analytics script, no advertising pixel, and no third-party tracker on this site.
the cookie banner you saw on your first visit recorded your choice in your browser's local storage. if we ever add optional analytics in future, only users who accepted will be measured. re-open the cookie banner to change your choice at any time.
children
blank is not intended for anyone under 18. we do not knowingly collect personal data from children. if you believe a minor has provided us with personal data, contact us and we will delete it.
security
we protect your information with industry-standard security measures, including encryption in transit, encryption at rest for sensitive credentials such as your trading 212 api key, and access controls that limit who at certified random can see your data. no system is perfectly secure, so we encourage you to use a strong, unique password and to keep your devices safe.
changes to this policy
we may update this policy from time to time. the date at the top of this page always reflects the last revision. if we make material changes we will notify you in the app or by email before they take effect.
