In short: FolderLocker is a Windows desktop app that locks and hides folders on your own PC. The free edition is free to use within its limits. Pro removes those limits and is sold as a one-time purchase with a license key: you pay once, you keep the license, and we — Zepker — handle your order, your invoice, and any refund you are entitled to. The app protects folders with Windows file-system permissions, not encryption — please read Section 7 before you rely on it.
FolderLocker ("the App") is designed, developed, and published by Zepker, an independent software studio ("we", "us", "our"). These Terms of Service ("Terms") are a legal agreement between you and Zepker, and they apply when you download, install, activate, purchase, or use the App, the FolderLocker Recovery tool, or this website.
These Terms cover the App itself, the Pro license and license key, this website, and your purchase of a license from us. They do not cover the Microsoft Store — your use of the Store is governed by Microsoft's own terms and by the Standard Application License Terms supplied with the Store package.
By installing or using the App, or by completing a purchase, you confirm that you have read and accept these Terms. If you do not accept them, please do not use the App and uninstall it.
You must be at least 18 years old, or the age of legal majority where you live, to buy a license. If you use the App on behalf of a company, you confirm that you are authorised to accept these Terms for that company.
The App is the same program in both editions. Pro does not unlock a different kind of protection — it removes the numerical limits on how many folders you can protect at the same time.
| Edition | What you get | Cost |
|---|---|---|
| Free | All locking, hiding, unlocking, and recovery features, Windows Hello and password verification, the recovery tool — but at most 3 locked folders and 1 hidden folder at any one time. | Free, for personal or commercial use. |
| Pro | Unlimited locked folders and unlimited hidden folders. Everything else is identical. | One-time purchase with a license key (portable edition) or a Microsoft Store add-on. |
The free limits count only folders that are currently locked or hidden. Unlocking a folder frees its slot. Folders you have already locked can always be unlocked, whatever your license status — including after a refund, an expired activation, or a failed license check. We will not use a folder's locked state as leverage to make you pay.
Free-edition limits may change in future versions. If we lower a limit, folders you have already locked stay locked and stay unlockable.
When you buy Pro, you receive a personal, worldwide, non-exclusive, non-transferable, non-sublicensable license to install and use the Pro edition of the App for lawful purposes, subject to these Terms and to the activation limit shown at checkout.
You may not sell, rent, lease, lend, share, publish, or redistribute your license key or the App itself, and you may not use one key to serve multiple people who each expect their own license. Keys found published publicly may be disabled.
When you buy Pro for the portable edition, your license key is issued after payment is confirmed and sent to the email address you enter at checkout. It is also shown once on the confirmation page.
For activation, the App sends your license key and a generated instance name (by default your computer name, so you can recognise the entry) to our licensing server. It does not send your files, folder names, or folder paths. See the Privacy Policy.
If you lose your key, read the original email first. If it is gone, contact us from the purchase email address with your order ID and we will help you recover access. We can only send license information to the email address that was used for the purchase, and we never issue a second key in place of an existing one.
Using a key that you did not buy, generating keys, patching the App to skip activation, or blocking activation checks to exceed the activation limit is a breach of these Terms and may result in the key being disabled.
Pro for the portable edition is digital content delivered immediately. By completing checkout and receiving your key, you ask for the license to be delivered right away and you acknowledge that, where a statutory right of withdrawal applies to digital content (for example in the EU or the UK), that right is lost once the key has been delivered and activation has begun.
Even so, we apply the following refund policy as a matter of goodwill:
Refunds and returns for the Microsoft Store edition are handled by Microsoft under Microsoft's own refund policy. We cannot refund, cancel, or transfer a Store purchase, and we cannot see your Store payment details.
We would rather you understand this before you rely on it:
FolderLocker$FolderLocker) on the same drive, leaving a small .flock placeholder at the original location. The files themselves are not encrypted.You are responsible for:
Please do not use FolderLocker as the only protection for data that is irreplaceable, or in an environment with legal or regulatory retention requirements, without also using proper encryption and backups. The App is a convenience tool for everyday privacy on a personal PC, not a compliance or forensic-security product.
You agree not to:
Using the free edition at work, on a business PC, or for commercial purposes is allowed within the free limits — no separate commercial license is required.
The App has no account system, no telemetry, no analytics, and no cloud service. Your folders and files never leave your computer. What the App stores locally, and the very limited data involved in a purchase or license activation, are described in the Privacy Policy, which forms part of these Terms.
To the maximum extent permitted by law, the App is provided "as is" and "as available", without warranties of any kind, whether express, implied, or statutory, including any implied warranty of merchantability, fitness for a particular purpose, title, or non-infringement. We do not warrant that the App will be uninterrupted or error-free, that every defect will be corrected, or that a locked folder can be restored in every conceivable situation (for example after disk failure, file-system corruption, or deletion of the App's data by other software).
Nothing in these Terms excludes or limits any warranty or right that cannot be excluded or limited under the mandatory law of your country of residence. If you are a consumer in the EU or the UK, you keep your statutory rights in relation to digital content that is not as described or not of satisfactory quality.
To the maximum extent permitted by law, and except as stated below, we are not liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, loss of profits, loss of business, business interruption, or the cost of substitute software, arising out of or relating to the App or these Terms — whether based on warranty, contract, tort (including negligence), or any other legal theory, and even if we have been advised of the possibility of such damage.
Our total aggregate liability for all claims relating to the App or these Terms is limited to the amount you actually paid us for the license concerned (or, for the free edition, to zero, to the extent permitted by law).
Nothing in these Terms limits or excludes liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, for gross negligence or wilful misconduct, or for any other liability that cannot be limited or excluded by law.
You may stop using the App at any time; unlock your folders first, then uninstall it. These Terms apply for as long as you use the App.
We may suspend or terminate your license if you materially breach these Terms — for example by redistributing the App, publishing or sharing a key, cracking activation, or committing payment fraud. Where it is reasonable to do so, we will contact you first and give you a chance to fix the problem.
If your license ends, the App continues to work with the free-edition limits, and every folder you have already locked can still be unlocked. Termination does not entitle you to a refund where the breach was yours, and it does not affect any provision that by its nature should survive (for example Sections 3, 7, 11, 12, and 16).
If you install the App from the Microsoft Store, the Microsoft Store Terms of Use and the Standard Application License Terms apply to that copy, in addition to these Terms. Where they conflict, the Microsoft terms prevail for the Store copy.
We may update these Terms when the App changes — for example when we add a payment channel or a new edition. The current version is always on this page, with the "Last updated" date at the top. Material changes will be summarised here before they take effect; if a change is significant, we will also mention it in the App's release notes.
The Terms that apply to your purchase are the ones in force on the day you bought it, unless the law requires otherwise or you accept the newer version by continuing to use the App.
Talk to us first. Most issues are resolved in one email. Write to support@zepker.com with your order ID if you have one; we aim to answer within 30 days.
These Terms are governed by the laws of the country in which Zepker is established, without regard to its conflict-of-law rules and excluding the UN Convention on Contracts for the International Sale of Goods. Nothing in this section deprives you of the protection of mandatory rules — including consumer-protection rules — of the country in which you have your habitual residence, and consumers in the EU, the UK, and elsewhere may bring proceedings before their local courts where the law gives them that right.
If any provision of these Terms is found unenforceable, it will be limited or removed to the minimum extent necessary, and the remaining provisions stay in full force.
These Terms, together with the Privacy Policy, are the entire agreement between you and us about the App, and replace any prior statement on this website or in the App.
