Privacy Policy

Last updated October 22, 2026

This policy explains what personal data [Company legal name] (“PrevLint”, “we”, “us”) collects when you use PrevLint, why we collect it, who we share it with and what choices you have.

In short: we collect what we need to run your account, your creations and your purchases. We send your prompts and files to AI providers to generate results. We don’t sell your data or show ads, and you can ask us to delete your account at any time. Using PrevLint is also covered by our Terms of Service.

1. What we collect

Information you give us

  • Account: your email address, name and password. Your password is stored hashed by our sign-in provider, so we can’t see it. If you sign in with Google, we receive your name, email address and profile picture from Google.
  • Profile: your username, plus anything you add, such as a bio, avatar, banner, website, location and social links.
  • Creations: models, images and project folders you upload; your AI Studio canvases, prompts, reference images and chats with the assistant; and the images, 3D models, videos and audio you generate.
  • Community activity: comments, upvotes, poll votes and feedback you send.
  • Purchases: Lemon Squeezy collects your payment details. We receive the order details, such as the order reference, the pack, the amount, the status and any refund, and link them to your account.
  • Messages: what you send us by email.

Information collected automatically

  • Credit history: each credit pack purchase, generation charge, marketplace purchase or sale, and refund.
  • Technical data: your IP address, browser and device type, and the pages and requests you make. Our hosting, rate limits and bot checks use this.
  • Error reports: when something breaks, we receive details of the error, your browser, the page and possibly your account ID and IP address, along with a short replay of the page around the error. Text and form inputs are masked in the replay.
  • Cookies and browser storage: see section 6.

2. How we use it

  • To run PrevLint: your account, storing and showing your creations, and running your generations and chats.
  • To process purchases and keep your credit balance correct.
  • To keep PrevLint safe: preventing spam, fraud and abuse, and enforcing our Terms.
  • To find and fix bugs and to improve features.
  • To send service emails, such as confirming your email, resetting your password and telling you about important changes. We won’t send you marketing emails without your consent.
  • To meet legal obligations, such as keeping tax records.

We don’t sell your personal data, share it for advertising or show ads. We don’t train AI models on your content.

3. AI providers

When you generate something or chat with the assistant, we send what the request needs to an AI provider:

  • fal.ai runs the image, 3D, video and audio models. Your prompt, reference images and settings go to fal.ai and to the company that made the model you chose, such as Tencent (Hunyuan), Meshy, Tripo, Google, ByteDance, MiniMax or ElevenLabs.
  • DeepSeek powers the assistant. Your chat messages and details of the items on your canvas, such as their names, prompts and links, go to DeepSeek, which is based in China.

Each provider handles this data under its own terms and privacy policy. Please don’t put sensitive personal information in prompts or chats.

4. Who we share it with

We use these service providers to run PrevLint. Each gets only what it needs for its job:

  • Supabase: Database, sign-in and file storage, hosted in the US (Virginia).
  • Vercel: Website hosting.
  • fal.ai: Runs the image, 3D, video and audio models, together with the company that made the model you choose.
  • DeepSeek: Powers the AI Studio assistant. DeepSeek is based in China.
  • Lemon Squeezy: Payments, as our merchant of record.
  • Google: Sign-in with Google, if you use it.
  • Cloudflare Turnstile: Bot checks on the sign-in and sign-up forms.
  • Upstash: Rate limits. Stores your account ID or IP address for a short time.
  • Sentry: Error reports.

We may also share data:

  • with other users and the public, as described in section 5;
  • when the law requires it, or to protect the rights, property or safety of our users, the public or us;
  • with a buyer or successor if PrevLint is merged, acquired or sold. We’ll tell you before your data moves under a different privacy policy.

5. What other people can see

  • Your profile: your username, name, avatar and the other profile details you fill in.
  • Items you publish publicly, your comments and upvote counts.
  • Private items are hidden from other users and aren’t listed anywhere in PrevLint. Their files are stored at unlisted links, though, and anyone who has the exact link can open the file. Don’t share those links, and don’t upload highly sensitive material.

6. Cookies and browser storage

We use cookies to keep you signed in and secure. Browser storage remembers some preferences, such as your layout. Cloudflare Turnstile may use cookies and device signals to tell people from bots. We don’t use advertising or analytics trackers.

7. How long we keep it

  • We keep your account data and content while your account is open.
  • When you delete an item or chat, we remove it from PrevLint. Copies may stay in backups for a limited time.
  • When your account is deleted, we delete or anonymize your data within 30 days. Purchase records are kept, no longer linked to your account, for as long as tax and accounting law requires.
  • We can’t recall copies that other users have already downloaded.
  • Error reports and server logs are kept by our providers for a limited time.

8. Security

We use encrypted connections, access rules on our database and limited access to production systems. No system is perfectly secure, so please use a strong, unique password.

9. Your choices and rights

  • You can change your profile and settings, and delete your items and chats, from your dashboard.
  • To get a copy of your data, correct it or delete your account, email [contact email] from the address on your account. We’ll reply within 30 days and may need to confirm it’s you.
  • If you’re in the EEA, the UK or another place with similar laws, you also have the right to restrict or object to how we use your data, to take your data elsewhere, to withdraw consent you gave, and to complain to your local data protection authority. We rely on these legal bases: running our agreement with you, our legitimate interests in keeping PrevLint safe and working, legal obligations, and your consent where we ask for it.
  • We don’t sell or share personal information for targeted advertising, and we won’t treat you differently for using your privacy rights.

10. International transfers

We’re a US company, and your data is mainly stored in the US. Some providers process it in other countries, such as DeepSeek in China, and our team may access it from other countries, including Mongolia. Data protection laws in those countries may differ from the laws where you live.

11. Children

PrevLint isn’t for children under 13, and we don’t knowingly collect their data. If you believe a child under 13 has given us personal data, contact us and we’ll delete it.

12. Changes to this policy

When we change this policy, we update the date at the top. For significant changes, we’ll also tell you by email or on the site before they take effect.
