Privacy Policy
Effective date: April 26, 2026
This policy explains how Solvequill collects, uses, and safeguards your personal data.
1. Who We Are
Solvequill ("we," "us," "our") operates an educational platform that turns user-submitted problems into AI-generated explanation videos and study tools. This Privacy Policy explains what personal data we collect, how we use it, who we share it with, how long we keep it, the legal bases on which we rely, and the rights you have over your data.
2. Information You Provide
When you create an account we collect your full name, email address, password (stored only as an irreversible hash), preferred language and theme, time zone, marketing or research preferences if you opt in, and any role, education stage, primary subject, or onboarding answers you choose to share. When you submit problems, we collect your text, photos, screenshots, PDFs, source files, optional notes, requested style, subject and difficulty hints, and the language you choose for the explanation. When you contact support, share to Explore, report a problem, leave feedback, or accept legal terms, we record the relevant content, timestamp, and version of the document accepted.
3. Information Collected Automatically
When you use Solvequill we automatically collect technical data that helps us run, secure, and improve the Service: IP address, approximate region derived from IP, browser and operating-system identifiers, device type, screen size, referring page, in-app interaction events (such as button clicks and page views), error and crash reports, performance metrics, request timing, and identifiers from session, security, and core preference cookies. We do not use third-party advertising trackers.
4. Information Generated by the Service
As the Service processes your input we generate further data: extracted question text, structured solution steps, intermediate AI prompts and responses, generated audio narration, rendered video files, summaries, key concepts, mistakes lists, study plans, quizzes, practice problems, queue and processing telemetry, fairness/abuse signals, quota counters, and Explore metadata when you publish.
5. How We Use Information
We use information to: create and authenticate your account; deliver and personalize features; generate, store, and serve videos and study tools; calculate and enforce plan quotas; process payments and prevent fraud once paid plans are enabled; communicate transactional messages such as verification codes and account notices; respond to support and feedback; investigate and remediate abuse, security incidents, or service errors; comply with legal obligations and lawful requests; conduct internal research and improve our models, prompts, and product; and enforce our Terms of Service.
6. Legal Bases (EEA, UK, and equivalent jurisdictions)
Where data protection laws such as the GDPR or UK GDPR apply, we rely on the following legal bases: performance of a contract (creating your account, processing your problems, delivering videos), legitimate interests (security, fraud prevention, service improvement, infrastructure operation), legal obligation (tax, accounting, responding to lawful requests), and consent (optional cookies, marketing communications, research participation). You may withdraw consent at any time without affecting the lawfulness of processing carried out before withdrawal.
7. AI Processing and Service Providers
To operate the Service we share your inputs and selected metadata with carefully selected sub-processors, only to the extent needed to deliver the requested feature. Categories include: cloud infrastructure and storage providers; database providers; large-language-model and computer-vision API providers used to read questions and generate solutions; text-to-speech and audio-processing providers; video rendering and asset-pipeline providers; transactional email providers; payment providers (when paid plans are active); error-monitoring and analytics providers; security and abuse-detection providers. Sub-processors are bound by contractual confidentiality and data-protection terms. We do not sell your personal data to third parties, and we do not use your submissions to train third-party general-purpose models for unrelated commercial purposes.
8. International Transfers
Sub-processors and infrastructure may operate in countries different from your own, including outside the European Economic Area, the United Kingdom, or Türkiye. Where required, transfers rely on appropriate safeguards such as Standard Contractual Clauses, adequacy decisions, or equivalent legal mechanisms. You may request a copy of the safeguards relevant to your transfer.
9. Cookies and Similar Technologies
We use a small number of strictly necessary cookies for authentication, session continuity, security, and core preferences (language, theme, last-used video language). Where we use optional analytics or research cookies, we present a clear consent prompt and respect your choice. You can clear or block cookies through your browser settings, but doing so may break sign-in, video playback, or other features that depend on session identifiers.
10. Data Retention
We retain personal data only as long as necessary for the purposes set out in this policy, to comply with legal obligations (tax, accounting, anti-fraud, regulatory record-keeping), to resolve disputes, to enforce our agreements, and to protect rights and safety. Active account data is kept while your account is active. After deactivation, content and generated outputs may be retained per the retention rules described in our Terms (Section 12). Backups, audit trails, security logs, and abuse-prevention records may persist on a rolling schedule even after deletion.
11. Your Rights
Subject to your jurisdiction, you may have rights to access, rectify, delete, restrict, port, or object to our processing of your personal data, and to withdraw consent or opt out of marketing or optional cookies. To exercise a right, contact us through the Contact page within the Service. We may need to verify your identity before fulfilling a request and may decline requests where doing so would undermine the rights of others, our legal obligations, or the integrity of security and audit records. We aim to respond within statutory timeframes and within thirty days where no specific timeframe applies.
12. Children's Privacy
Solvequill is intended for users who can lawfully consent to processing of personal data in their country. We do not knowingly collect data from children below the applicable minimum age without parental, guardian, or school authorization. If you believe a child under that age has provided personal data without authorization, contact us and we will take appropriate steps to remove the data.
13. Security
We apply reasonable technical and organizational safeguards, including encryption in transit, password hashing, access controls, audit logging, segregated environments, dependency monitoring, and incident response procedures. No system is completely secure. If you suspect unauthorized access to your account, contact us immediately.
14. Data Breach Notification
If a personal data breach occurs that is likely to result in a risk to the rights and freedoms of affected users, we will notify the competent supervisory authority and affected users in line with applicable law and within the legally required timeframes.
15. Automated Processing
Solvequill applies automated processing to extract questions, generate solutions, render videos, score quizzes, and detect abuse. These automated steps do not produce decisions with legal or similarly significant effects on you. If we ever introduce processing that meets that threshold, we will inform you and provide the rights required by applicable law.
16. Changes to This Policy
We may update this Privacy Policy as the Service evolves. Material changes will be communicated through the Service or by email at least seven days before taking effect, where reasonably practicable. Continued use of the Service after the effective date of an updated policy constitutes acceptance of the changes.
17. Contact
Questions, requests, or concerns about this policy can be sent through the Contact page within the Service. We will route privacy requests to the team responsible for handling them.
