Welcome to MarkM8 ("we", "us", "our"). Your privacy is of paramount importance to us. This Privacy Policy explains how we collect, use, store, and protect your personal data when you use our website and services (collectively, the "Platform"). MarkM8 is committed to safeguarding your information in accordance with the UK General Data Protection Regulation ("UK GDPR"), the Data Protection Act 2018, and other applicable data protection laws.
By using our Platform, you agree to the terms of this Privacy Policy. If you do not agree, please do not use our services.
MarkM8 is the data controller responsible for your personal data.

We collect and process the following categories of data:
Special Category Data: We do not require or intentionally collect "special category" data (e.g., ethnicity, health, political views) except where explicitly provided for accessibility or support reasons (e.g., ADHD, dyslexia), and only with your explicit consent.
We process your data only where we have a lawful basis. Main purposes include:
AI Processing & Model Improvement: Our Platform uses artificial intelligence to generate assignment feedback and grade predictions. Your essay submissions may also be used, in an anonymized and aggregated form, to improve our AI models. We will always seek your explicit consent before using your data for this purpose beyond providing your requested feedback.
We use Google OAuth as our identity provider for user authentication. When you sign in, your name and email address are collected directly from your Google account with your consent. Google may also set cookies as part of this process. For more details, please refer to Google's Privacy Policy.
We use Stripe to process payments securely. When you make a payment, your payment information (such as credit/debit card number, billing address, and other relevant data) is transmitted directly to Stripe. We do not store your full card details on our servers.
Stripe processes your data in accordance with their own Privacy Policy, which you can review here. Stripe may transfer data outside the UK/EEA, but will ensure appropriate safeguards are in place, such as Standard Contractual Clauses or UK International Data Transfer Agreements.
Auto-Reload Feature: If you choose to enable our auto-reload feature for purchasing credits, you will be asked to provide explicit consent. You can disable this feature at any time in your account settings. We only retain Stripe's customer or token reference, never your card details.
We may use analytics services such as Google Analytics 4 and/or PostHog to collect aggregated usage statistics and help us improve our Platform. We may also use external providers to send emails, notifications, or service updates.
These providers process your data only as instructed by us and in compliance with GDPR, and their privacy policies will be made available on request or in future policy updates.
We use the OpenAI API to process and provide AI-generated feedback and grades. Essay texts submitted for feedback are sent to OpenAI's servers. OpenAI may process this data outside the UK/EEA (e.g., in the United States), but contractual safeguards such as Standard Contractual Clauses are in place to protect your data in compliance with GDPR.
OpenAI acts strictly as a processor and does not use your data for its own model training or improvement. For more information, see OpenAI's Privacy Policy.
Some of our service providers (including Stripe, OpenAI, Google, and analytics/email partners) may process your data outside the UK or EEA. In these cases, we ensure that appropriate safeguards—such as Standard Contractual Clauses or the UK International Data Transfer Agreement—are implemented to protect your data.
MarkM8 performs regular Data Protection Impact Assessments in line with the requirements of the UK GDPR. DPIAs are conducted for all major data processing activities—especially those involving student data and automated decision-making—to identify, assess, and mitigate privacy risks. The goal is to ensure that all personal data processing is fair, necessary, proportionate, and secure.
