Terms of Service

Last updated: October 7, 2026

1. Scope

These Terms of Service govern the use of the BlindLock software application ("Software") provided by BlindLock, LLC ("Provider"). By purchasing and using BlindLock, you agree to these terms.

2. Contract Formation

Sales and payment processing run through Polar Software, Inc. (“Polar”) as external Merchant of Record. The contract is formed upon completion of the purchase through Polar, which acts as the seller towards customers. After successful payment, you will receive a licence key by email.

3. Licence

A valid paid licence key grants you a personal, non-exclusive right to use the Software on one desktop device at a time (Windows, macOS or Linux). You cannot pass this right on to other persons. The licence is bound to your hardware. You can move it to a replacement device with BlindLock’s built-in migration. The upcoming iOS, iPadOS and Android editions will be free of charge and will not require a paid desktop licence key.

4. Lifetime Licences

A Lifetime licence is paid once and has no expiry date or recurring subscription. It includes all released updates and major versions at no additional charge. Licence entitlement is still validated online. Every update is mandatory. Once a new version is released, BlindLock opens the vault only after it is installed. Subscription licences entitle you to use the Software while the subscription is active.

5. Activation and Connectivity

BlindLock requires an internet connection for initial activation and every new unlock session, when licence entitlement and version status are checked. If the Software cannot reach the licence service, a new unlock can only be completed with a device-bound permit previously issued by the licence service. That permit is valid for up to seven days from the last successful server contact. After that, a new unlock requires renewed server contact. Once unlocked, the vault continues to operate locally until that session closes.

6. Your Data

BlindLock stores passwords, notes and 2FA secrets encrypted inside a PNG carrier on your device. Larger files use separate encrypted file-vault containers. BlindLock, LLC has no central access to these vault contents or their encryption keys and never receives them on its servers. Vault contents leave your device only through an action you choose, such as an export or a backup in a cloud-synchronised folder. You are responsible for the active carrier, encrypted backups, file-vault recovery materials, password and recovery phrase. BlindLock, LLC cannot recover lost secrets or recovery material.

7. Warranty

Statutory warranty rights under applicable consumer protection laws apply. The Provider warrants that the Software conforms to the contractual requirements at the time of delivery. The warranty period is two years from delivery.

The Provider will provide updates necessary to maintain the Software's conformity and will inform you about their availability.

8. Limitation of Liability

The Provider is liable without limitation for damages caused by intent or gross negligence, and for damages arising from injury to life, body, or health. For slight negligence, the Provider is liable only for breach of material contractual obligations, limited to foreseeable, contract-typical damages. All further liability is excluded to the extent permitted by law.

The Provider is not liable for data loss resulting from hardware failure, forgotten PINs, or lost recovery phrases.

9. Prohibited Use

You may not:

10. Termination

The Provider may terminate your licence if you violate these terms. Upon termination, your right to use the Software ends immediately. Your locally stored data remains on your device but may become inaccessible without an active licence.

11. Right of withdrawal

Right of withdrawal

The following information applies to consumers whose habitual residence is in the European Union.

You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day the contract is concluded.

To exercise your right of withdrawal, you must inform us (BlindLock, LLC, 131 Continental Dr, Suite 305, Newark, DE 19713, USA, email: info@blindlock.app) of your decision to withdraw from this contract by an unequivocal statement (for example an email).

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. The seller is Polar Software, Inc., 3500 South DuPont Highway, Dover, DE 19901, USA. We forward your statement to Polar for processing.

Effects of withdrawal

If you withdraw from this contract, Polar as the seller reimburses all payments you made for this contract without undue delay and no later than fourteen days from the day on which we are informed about your decision to withdraw. The same means of payment you used for the initial transaction is used for this reimbursement, unless you have expressly agreed otherwise. You will not incur any fees as a result of the reimbursement.

Early expiry of the right of withdrawal

Under Art. 16(m) of the EU Consumer Rights Directive (2011/83/EU), for contracts for the supply of digital content not delivered on a tangible medium, your right of withdrawal expires once the Provider has begun performing the contract after you have (a) expressly consented to the Provider beginning performance before the withdrawal period ends and (b) acknowledged that your consent means you lose your right of withdrawal once performance begins. For BlindLock this means: once you give this consent at checkout and the download or licence key is made available, the right of withdrawal ends. Before payment, Polar’s checkout shows a required checkbox for this: “I want BlindLock to be delivered immediately and I understand that I lose my right of withdrawal once delivery starts.” Without this tick the purchase cannot be completed.

12. Dispute Resolution

13. Governing Law

These terms are governed by the law of the Provider's seat, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). For consumers habitually resident in the EU, the mandatory consumer protection provisions of their country of residence remain unaffected.

14. Severability

If any provision of these terms is or becomes invalid, the validity of the remaining provisions shall not be affected.
