Privacy Policy

Last updated: May 24, 2026

1. Introduction

Promto ("we," "our," or "us") operates two related products: the website at promto.io and the Promto mobile app (iOS and Android). They serve different purposes and collect different types of data. This policy is split into separate sections for each product, plus general terms that apply to both.

2. promto.io (Website)

Applies when you visit or use promto.io in a browser (including when installed as a PWA).

2.1 Information we collect

  • Account data: When you sign up (e.g. via email or third-party auth), we store account identifiers and profile information such as display name, username, avatar, bio, and social links you add.
  • Content you create: Prompts, images you upload or generate, and other content you publish on the platform.
  • Activity data: Likes, dislikes, follows, and interactions with posts and creators to power the feed and recommendations.
  • Payment and credits: Purchase history and credit balance. Payment processing is handled by Lemon Squeezy; we do not store your full payment card details.
  • Technical data: Logs, device and browser information used for security, analytics, and improving the service.

2.2 How we use your information

  • Provide, operate, and improve promto.io
  • Personalize your feed (e.g. from follows and likes)
  • Process purchases and manage your credit balance
  • Attribute affiliate commissions to creators when you purchase after using their prompts
  • Send service-related communications (e.g. account or payment updates)
  • Enforce our terms, prevent abuse, and protect security
  • Comply with applicable law and respond to valid legal requests

2.3 Third-party services

  • Supabase: Authentication, database, and file storage for accounts and content.
  • Lemon Squeezy: Payment processing and affiliate payouts when you buy credits.
  • AI image generation: When you generate images, your prompt and related data are sent to our AI provider to produce the image.
  • Advertising (Google AdSense): We may show third-party ads. These partners may use cookies and similar technologies. See How Google uses data when you use our partners' sites or apps.

2.4 Cookies and similar technologies

We use cookies for session management, preferences, affiliate attribution (e.g. to remember which creator's prompt led you to a purchase), and advertising. You can control cookies through your browser settings; some features may not work if you disable them.

2.5 Data retention and security

We retain your data for as long as your account is active or as needed to provide the service, comply with law, and resolve disputes. We use appropriate technical and organizational measures to protect your data; no system is completely secure.

2.6 Your rights

Depending on where you live, you may have the right to access, correct, delete, or restrict use of your personal data. You can update your profile and account settings on promto.io. If you are in the EEA/UK, you may lodge a complaint with your supervisory authority.

3. Promto Mobile App

Applies when you use the Promto app on iOS or Android. This is separate from the website experience.

3.1 What the app offers

The mobile app is for browsing and discovering prompts. Unlike promto.io, the app does not offer account registration, sign-in, or in-app purchases. Credits, subscriptions, posting, and image generation are only available on the website.

3.2 Information we collect

  • On your device only: Theme preference (light/dark), posts you save as favorites, and cached feed or post content for offline browsing. This stays on your device unless you clear app storage or uninstall the app.
  • From our servers: When you browse or search, the app loads public posts and metadata from our APIs. We may log standard technical data (e.g. IP address, device type, app version) for security and reliability.
  • We do not collect via the app: Account credentials, profile data, payment details, purchase history, credit balance, likes tied to an account, or content you publish.

3.3 How we use your information

  • Show feeds, search results, and post details
  • Cache content so you can browse offline
  • Remember your theme and favorites on your device
  • Maintain security and fix technical issues

3.4 Third-party services

The app loads public content from our backend (hosted with Supabase). We do not use Lemon Squeezy, AI generation providers, or advertising partners inside the app itself. If you open promto.io in your browser from the app, the website section of this policy applies to that session.

3.5 Local storage (not cookies)

The app uses on-device storage (not browser cookies) for preferences, favorites, and offline cache. You can remove this data by clearing the app's storage or uninstalling the app.

3.6 Data retention and security

Data stored only on your device is deleted when you clear app data or uninstall the app. Server logs from app API requests are retained only as long as needed for security and operations, consistent with our website practices for anonymous technical logs.

4. General (Website and App)

4.1 Children

Our services are not directed at children under 13 (or the applicable age in your jurisdiction). We do not knowingly collect personal information from children. If you believe we have collected such information, please contact us so we can delete it.

4.2 Changes to this policy

We may update this Privacy Policy from time to time. We will post the revised version on this page and update the "Last updated" date. Continued use of promto.io or the app after changes constitutes acceptance of the updated policy.

4.3 Contact us

For privacy-related questions or requests about either the website or the app, contact us at the email or address provided on promto.io.
