Terms & Conditions

Effective Date: March 18, 2026  ·  Last Updated: August 12, 2026

1. Agreement to Terms

By downloading, installing, or using the Curltine mobile application ("App"), or by using our websites at curlyhair.app and curltine.com (including web signup and checkout), you agree to be bound by these Terms and Conditions ("Terms"). If you do not agree to these Terms, do not use the App or websites.

These Terms constitute a legally binding agreement between you ("User", "you") and Curltine ("we", "us", or "our"), the operator of the Curltine app and websites, reachable at [email protected].

2. Eligibility

You must be at least 13 years old (or 16 years old in the European Economic Area) to use the App. By using the App, you represent and warrant that you meet this age requirement.

If you are using the App on behalf of a business or organisation, you represent that you have the authority to bind that entity to these Terms.

3. Account Registration

3.1 Creating an Account

To use most features of the App, you must create an account by providing your name, email address, and a password. You agree to provide accurate, current, and complete information.

3.2 Account Security

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us immediately at [email protected] if you suspect any unauthorised access to your account.

3.3 Account Termination

We reserve the right to suspend or terminate your account at our discretion if you violate these Terms or engage in conduct we deem harmful to the App or other users.

4. Subscriptions and Payments

4.1 Free Plan

The App offers a free tier that includes limited access to hair scan and product scan features:

  • 1 hair scan per account (lifetime on free plan)
  • 1 product scan per account (lifetime on free plan)

4.2 Curltine Pro (Premium) Subscription

A Curltine Pro subscription unlocks expanded access, including more hair and product scans, personalised care plans, and full progress tracking. Limits depend on the plan you choose and are shown in the App and on our website at checkout.

Pro is available as a Weekly, Monthly, or Annual plan. Pricing is displayed in the App or on curltine.com at checkout.

4.3 Billing channels

Depending on how you subscribe, payment is processed in one of these ways:

  • In the App (iOS / Android): through the Apple App Store or Google Play. Those stores handle billing for in-app purchases. Payment is charged to your store account upon confirmation of purchase.
  • On the web (curltine.com): through Paddle.com Market Ltd (and/or its affiliates) as merchant of record. When you pay on the web, Paddle processes your payment, issues receipts, and handles applicable sales taxes.

Subscriptions automatically renew at the end of each billing period unless cancelled before renewal as described below.

4.4 Cancelling App Store or Google Play subscriptions

If you subscribed through the Apple App Store or Google Play, manage or cancel in your store account settings (for example, iPhone Settings → Apple ID → Subscriptions → Curltine, or the equivalent Google Play subscriptions screen). Cancel at least 24 hours before the end of the current period to avoid the next charge. You retain Pro access until the end of the period already paid for. Refund requests for store-billed purchases are handled by Apple or Google under their refund policies.

4.5 Cancelling web (Paddle) subscriptions

If you subscribed on curltine.com via Paddle, you can cancel auto-renewal through the subscription management link in your Paddle receipt or customer emails, or by contacting [email protected] and we will help you cancel. Cancellation stops future renewals. You keep access to Curltine Pro until the end of the period you already paid for, unless otherwise stated at checkout or required by law.

4.6 Refunds for web (Paddle) purchases

For web purchases processed by Paddle, refund requests are reviewed by Curltine and/or Paddle under applicable law and Paddle's buyer policies. To request a refund, email [email protected] with the email used at checkout and your order or transaction details from your Paddle receipt. We aim to respond within a few business days. Nothing in these Terms limits any mandatory consumer rights that apply in your country.

4.7 Failed payments and renewals

If a renewal payment fails, Paddle or the app store may retry the charge and/or send payment update reminders. Access to Pro features may be limited until billing succeeds or the subscription ends.

4.8 Price Changes

We may change subscription pricing at any time. If we increase prices for an active subscription, we will notify you in advance and your new rate will apply at the next renewal. Continuing to use the App after a price change constitutes acceptance of the new price.

4.9 Scan Limits

Scan limits (for both free and premium tiers) are enforced according to your plan (for example weekly or monthly counters). We reserve the right to adjust these limits at any time with reasonable notice to users.
