If you are accepting these Terms of service ('Terms') on behalf of a corporate entity, you represent and warrant that you possess the requisite legal authority to bind such entity.

Your continued use of the Services constitutes irrevocable acceptance of these Terms. If you do not agree to these Terms in their entirety, you must immediately discontinue all access to and use of the Services.

We reserve the right to modify these Terms at our discretion. Material changes will be communicated via the Services or email. Continued use post-modification constitutes acceptance of the amended Terms.

Reminda employs a zero-knowledge, End-to-End Encryption (E2EE) framework utilizing client-side AES-256-GCM cryptography. You retain all right, title, and interest in and to the content you submit ('User Data').

• Passphrase and key management: Cryptographic keys are derived locally on your device via PBKDF2 using your designated passphrase. Reminda's infrastructure never transmits, receives, or stores your master passphrase or unencrypted decryption keys.

• Absolute assumption of risk: Due to the zero-knowledge nature of the Services, Reminda is technically incapable of resetting your passphrase or recovering encrypted User Data in the event of credential loss. You bear sole and exclusive responsibility for safeguarding your recovery keys.

• Disclaimer of data loss: Reminda expressly disclaims any and all liability for permanent data loss resulting from forgotten, misplaced, or compromised passphrases.

The Services integrate artificial intelligence ('AI') functionalities, including automated context extraction and flashcard generation, processed via third-party API endpoints.

• Zero model training guarantee: We deploy strictly zero-retention API policies. Your User Data, private notes, and study materials are never utilized to train, fine-tune, or improve our or any third party's foundational machine learning models.

• Output disclaimer: AI-generated outputs are provided on an 'as is' basis strictly for cognitive learning assistance. Reminda makes no warranties regarding the accuracy, completeness, or reliability of these outputs. You are solely responsible for independently verifying any technical, medical, legal, or factual information.

• Subscription terms: Access to premium features requires a paid subscription. Fees are billed in advance on a recurring, periodic basis (monthly or annually) depending on your selected plan.

• Automatic renewal: Unless affirmatively cancelled prior to the conclusion of the current billing cycle, your subscription will automatically renew at the then-applicable rate. You authorize Reminda and its designated merchants of record (e.g., Paddle, RevenueCat, Apple, Google) to charge your payment method on file.

• Refund policy: Subject to mandatory consumer protection laws, new subscribers may request a full refund within thirty (30) days of their initial purchase by contacting billing@reminda.ai. Following this period, all payments are non-refundable.

• Prorations and taxes: Upgrades are prorated. You are responsible for all applicable taxes, levies, or duties imposed by taxing authorities related to your purchase.

Apple is not responsible for addressing any claims relating to the Services or your possession and/or use of the Services, including product liability claims, failure to conform to legal requirements, and intellectual property infringement claims.
