Who is responsible
B12 Insight operates b12cardio.com and is responsible for the personal information described in this policy. In this policy, “we”, “us” and “our” refer to B12 Insight.
| Item | Details |
|---|---|
| Data controller | B12 Insight, operator of b12cardio.com |
| Privacy contact | 2447598896jin@gmail.com |
| Legal entity and registered address | Available from the privacy contact on request |
This policy covers the website, the B12 risk check, report purchases, reports and support. It does not apply to third-party websites or services that have their own privacy notices.
Information we collect
We collect the information needed to run B12 Insight, deliver a requested report and keep the service secure. The main categories are:
| Category | Examples |
|---|---|
| Account information | Name, email address, password hash, email verification status, sign-in sessions, language and account preferences. |
| Check and report information | Your seven self-assessment answers, score, risk band, unlock status, related credit and dates. The detailed report is generated from these saved answers when you open or download it. |
| Purchase information | Order and transaction identifiers, report credits, amount, currency, payment status, payment provider and the email used for the order. |
| Support information | Ticket title, messages, image attachments and the replies needed to resolve your request. |
| Technical and security information | IP address, browser and device type, request time, pages requested, error logs and security events. |
| Referral and campaign information | UTM campaign tags, referring page, sign-up source and an approximate country or region derived from the connection. |
| Browser storage and preferences | Language, theme, cookie choice and unfinished check answers stored locally before you sign in. |
Keep medical records out of the check
The check uses fixed choices only. Do not send medical records, clinician letters, test PDFs or another person’s data. If you use a report credit for another adult, do so only with their knowledge and permission.
What the check asks and how it is stored
We designed the check to collect as little as possible. It asks seven fixed questions:
- Your age band: under 40, 40 to 59, or 60 and over.
- Your diet pattern: regular animal foods, mostly plant-based, vegetarian or vegan.
- Long-term use of a proton-pump inhibitor, H2 blocker, metformin, both or neither.
- Conditions that affect absorption, including IBD, coeliac disease, gut inflammation, stomach or bowel surgery, atrophic gastritis or pernicious anaemia.
- How often you eat animal foods.
- Recent tiredness, brain fog, tingling, numbness, sore tongue or breathlessness.
- Whether you have had B12 tested and whether the result was normal, borderline, low or not tested.
We do not ask for full medical records, test PDFs, family history, insurance details, government ID, precise location, your contact list or a free-text medical history inside the check.
| Stage | What happens to your answers |
|---|---|
| Before you sign in | Answers are kept in local browser storage so you can see the free preview. They are not yet linked to an account. |
| When you continue with an account | The answers are sent to B12 Insight and saved with your account so the score can be kept and the report can be unlocked later. |
| When you unlock a report | The report is linked to your account and the report credit you spend. The payment provider receives order data, not your check answers. |
| When you download a report | The report is saved as an HTML file on your device. You control that file and should store it somewhere you trust. |
Your answers can relate to health and are treated as sensitive health-related information. We use them to calculate the score, generate the report you request from the saved answers, support your account and protect the service. Where law requires a specific legal basis, we rely on your consent or another lawful condition needed to provide the service you requested.
A screening aid, not a diagnosis
The score and report do not measure your vitamin B12 level, diagnose a condition or replace a blood test or qualified clinician. They describe how your fixed answers compare with published risk factors.
How and why we use information
| Purpose | Legal basis |
|---|---|
| Create and manage your account, run the check and deliver requested reports | Performance of a contract or steps taken at your request |
| Process payments, report credits, refunds and receipts | Contract, legal obligations and accounting requirements |
| Provide customer support and reply to privacy or account requests | Contract and our legitimate interests in helping users |
| Protect accounts, prevent fraud and keep the service secure | Our legitimate interests in security and service integrity |
| Measure page performance and understand aggregate site usage | Consent where required, otherwise our legitimate interests |
| Send verification, password, purchase, security and policy messages | Contract, legal obligations and our legitimate interests |
| Meet legal requirements and defend legal claims | Legal obligation and our legitimate interests |
We do not use your check answers for advertising, and we do not sell them. We do not currently create identifiable profiles from your answers for purposes unrelated to the report. Aggregate site analytics may show page visits and performance, but not the options you selected in the check.
Payments and report credits
B12 Insight sells one-time report credits. There is no subscription, automatic renewal or automatic top-up. One unused credit unlocks one report.
Checkout may be handled by Waffo Pancake as merchant of record or by another provider shown at checkout, such as Stripe, PayPal or Creem. Alipay and WeChat Pay may be available in CNY through a supported provider.
We receive the order details needed to confirm payment, issue credits and handle support, including the order number, amount, currency, payment status, provider and payment email. We do not receive or store your full card number or card security code. The payment provider handles that information under its own privacy notice.
Your check stays separate from payment
Payment providers receive order and buyer information needed for checkout. They do not receive your seven check answers. Your report remains tied to your B12 Insight account.
Retention and security
| Information | Retention approach |
|---|---|
| Account, check and report data | Kept while your account is active. After a verified account deletion request, we remove or anonymise the active records within the ordinary operational period unless the law requires us to keep something longer. |
| Orders, tax and refund records | Kept for the period required by accounting, tax and consumer law, which may be up to seven years. |
| Support records | Kept for up to 24 months after the request is closed, unless a longer period is needed for a dispute. |
| Security and platform logs | Retained according to our operational needs and provider settings, normally no longer than 12 months. |
| Browser storage | Controlled by you through your browser. Unfinished answers are removed after use or when you clear site data. |
Account deletion is currently handled manually after we verify control of the account. Download any report you want to keep first. Deleting your account may remove saved reports, unused credits and access to the service.
We use encryption in transit, access controls, password hashing, rate limits and security monitoring. No internet service can guarantee perfect security, but we review our controls and respond to incidents that may affect your information. If an incident is likely to create a legal notification duty, we will notify affected users and relevant authorities.
Your privacy rights
Depending on where you live, you may have the right to:
- Know what personal information we hold and how we use it.
- Access a copy of your information and correct inaccurate details.
- Delete your information or ask us to restrict or stop certain processing.
- Receive eligible information in a portable, machine-readable format.
- Object to processing based on legitimate interests and withdraw consent for future processing.
- Receive equal service when you exercise a privacy choice.
To make a request, email the privacy contact below or open an account support ticket. We may need to verify that you control the relevant account. We will respond within the period required by applicable law, normally within 30 days. Some rights have legal exceptions, and deleting account data may remove access to saved reports and unused credits.
As of this policy, we do not sell personal information or share it for cross-context behavioural advertising. If an advertising tool is introduced later, we will update this policy and the available consent choices. You may use an authorised agent where the law allows it, subject to identity verification.
Service messages and email
B12 Insight currently does not send promotional email campaigns. We use email for service messages that you request or need, such as address verification, password resets, purchase confirmations, security alerts and important policy updates.
If optional marketing is introduced, we will use a lawful basis, explain what you would receive and provide a working unsubscribe route. Service messages would remain separate from marketing. You can also contact us to ask about your email settings.
Children
The service is intended for adults aged 18 and over. We do not knowingly collect personal information from anyone under 18. If you believe a child has provided information, contact us and we will take appropriate steps to delete it.
Changes to this policy
We may update this policy when the service or the law changes. We will update the date at the top of this page. For a material change, we will provide a clearer notice by email or in the service before it takes effect where required.
