Terms of Service

1. Acceptance of Terms

By creating an account or clicking "I agree," you enter into a binding contract with Pavlenko Consulting OÜ on the basis of these Terms and our Privacy Policy. If you do not agree to these Terms in their entirety, you must not access or use the Service.

2. Service Description

PuzzlePiece.app is a partner intelligence platform designed to help users understand their partners through cycle science, mood patterns, and relationship health tracking. The Service includes:

• Cycle tracking and mood logging tools
• Relationship health scoring and multi-dimensional insights
• AI-powered coaching, predictions, and monthly reports generated using third-party AI models
• Google Calendar integration for schedule and context awareness
• A partner sharing system with granular, per-category consent controls

We may modify, suspend, or discontinue any feature or aspect of the Service where objectively justified (for example, to address security vulnerabilities, comply with legal requirements, or adapt to changes in third-party services). We will provide at least 30 days' advance notice via email before any material reduction in functionality. If you do not accept such a change, you may terminate your subscription and receive a pro-rata refund for any pre-paid period remaining after the effective date of the change.

3. Eligibility

To use the Service, you must meet the following requirements:

• You must be at least 13 years of age. In jurisdictions where the minimum age for digital services is higher under applicable law, that higher age applies. Users between 13 and 16 must have verifiable parental consent in accordance with the Estonian Personal Data Protection Act (PDPA) and the EU General Data Protection Regulation (GDPR).
• You must provide accurate, current, and complete information when creating an account.
• You may maintain only one account per person. Creating multiple accounts is prohibited.
• You must have the legal capacity to enter into a binding contract in your jurisdiction.

By using the Service, you represent and warrant that you satisfy all eligibility requirements above. We reserve the right to suspend or terminate accounts that do not meet these requirements.

4. Account Responsibilities

You are responsible for the security of your account and all activity that occurs under it. Specifically:

• Keep your login credentials (including magic link emails) secure and do not share them with any third party.
• You are solely responsible for all actions taken through your account, whether or not authorized by you.
• You must notify us immediately at support@puzzlepiece.app if you become aware of or suspect any unauthorized access to or use of your account.
• We will not be liable for any loss or damage arising from unauthorized use of your account where you have failed to maintain the security of your credentials.

5. Subscription Terms

5.1 Available Plans

All prices shown are in Euros (EUR) and are exclusive of any value-added tax (VAT) or other taxes that may apply in your jurisdiction. Where required by law, applicable taxes will be added at checkout.

• Free Tier: Basic features available without subscription. Premium features — including AI-generated insights, monthly reports, and advanced charts — require an active paid subscription.
• Partner Sync: €8.00 EUR per month or €72.00 EUR per year (recurring subscription). Grants full access to all premium features for the subscribing user.
• Gift of Understanding: €72.00 EUR one-time purchase. A Partner Sync subscription gifted to a partner via a redeemable link.
• Partner Access: Free, invitation-based access. Granted by a primary subscriber to their partner. Partner Access is tied to the primary user's active subscription and terminates automatically if that subscription lapses or is cancelled. The partner will receive at least 7 days' notice before Partner Access is terminated due to the primary subscriber's subscription lapsing.

5.2 Payment Processing

All payments are processed by Stripe, Inc. By providing payment information, you authorize us to charge the applicable fees through Stripe. Stripe's processing of your payment information is subject to Stripe's own Terms of Service and Privacy Policy.

5.3 Cancellation and Refunds

You may cancel a recurring subscription at any time from the Settings section of your account. Cancellation takes effect at the end of the current billing period; you will retain access to premium features until that date. Refund requests may be submitted to support@puzzlepiece.app and will be evaluated in good faith. This does not affect your statutory right of withdrawal described in Section 6 or any other mandatory consumer rights under applicable law.

5.4 Gift Terms

Gift of Understanding purchases are subject to the right of withdrawal described in Section 6. Prior to redemption, a gift link may be transferred to another person but may not be resold. Once a gift has been redeemed and the purchaser gave explicit consent to early commencement at checkout, the right of withdrawal is lost. Unredeemed gift links do not expire, but we reserve the right to honour them subject to continued operation of the Service.

5.5 Price Changes

We may change subscription prices where justified by changes in our costs (for example, increases in third-party AI provider fees, infrastructure costs, or applicable taxes). We will provide at least 30 days' advance notice via email of any price increase, specifying the new price and the date it takes effect. If you do not accept the new price, you may cancel your subscription before the change takes effect and receive a pro-rata refund for any pre-paid period remaining.

6. Right of Withdrawal

6.1 Your Right

If you are a consumer in the European Union or the European Economic Area, you have the right to withdraw from this contract within 14 days without giving any reason. The withdrawal period expires 14 days after the day of the conclusion of the contract (i.e., the date you subscribe or purchase a gift).

6.2 How to Exercise This Right

To exercise the right of withdrawal, you must inform us of your decision to withdraw from this contract by an unequivocal statement. You may use the model withdrawal form below, but it is not obligatory. Send your withdrawal to:

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

6.3 Effects of Withdrawal

If you withdraw from this contract, we shall reimburse all payments received from you without undue delay and in any event not later than 14 days from the day on which we are informed of your decision to withdraw. We will carry out the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

6.4 Early Commencement Exception

The Service is digital content not supplied on a tangible medium. If you give your express consent at checkout for the performance of the contract to begin during the withdrawal period and acknowledge that you will lose your right of withdrawal once the Service has been fully performed, you will not be entitled to withdraw after the digital content has been fully provided. If you withdraw before the Service has been fully provided, you will pay an amount proportionate to what has been provided until the time you communicated your withdrawal.

• Either party may unlink the partner connection at any time from their own account settings, without requiring the other party's knowledge or consent.
• If the primary subscriber's subscription lapses or is cancelled, the partner will receive at least 7 days' notice via email before Partner Access is terminated.
• You must not use Partner Access features to monitor, surveil, or track any individual who has not given their informed, voluntary consent to be connected through the Service.
