Join the server and open a purchase ticket. You will receive a license key after completing the transaction. **How many servers can I use one license on?** One license covers up to two server instances: * One **production server** (public-facing) * One **development or test server** (must be on a private/local IP - not publicly accessible) If you need eTools on a second public server, you will need to purchase an additional license. **Can I share my license key with someone else?** No. License keys are strictly personal and non-transferable. Sharing a key will result in immediate revocation without refund. See the [Terms of Service](/docs/etools/legal/terms-of-service.md) for details. **My server IP changed. Can I rebind my license?** Yes. Each license includes **5 rebind tokens** for its lifetime. One token is used per rebind request. Contact EproMC support in Discord to process a rebind. Once all 5 tokens are used, additional rebinds can be purchased separately. **Do major version updates require a new purchase?** Minor updates (bug fixes and features within the same major version) are included with your license at no extra cost. Major version upgrades (e.g., v1.x to v2.x) may require a new purchase. This will be announced in advance in the Discord server. *** ## Installation & Activation **Where do I put my license key?** Place your key in `plugins/eTools/license.yml` under the `key` field: ```yaml license: key: "EPROMC-XXXX-XXXX-XXXX" ``` Save the file and restart your server. **The plugin says my license is invalid. What's wrong?** Common causes: * The key was copied incorrectly - check for extra spaces or missing characters. * The license is bound to a different IP and needs a rebind. * The license was revoked due to a ToS violation. Open a support ticket in Discord if none of those apply. **The plugin shows "Invalid digital signature / MITM detected." What does that mean?** This error appears when the response from the license server cannot be verified. Possible causes: * A proxy or firewall is intercepting outbound HTTPS traffic. * The server's system clock is significantly out of sync. Check your firewall settings and system time, then restart the server. **Does the plugin need an internet connection to work?** Yes, on startup. eTools contacts the EproMC license server when the plugin loads. After successful validation, the plugin continues running normally even if the connection drops temporarily. A periodic heartbeat check runs in the background to maintain validation. **Can I run eTools on a local test server while also running it on my public server?** Yes, as long as the test server uses a private or local IP address (e.g., `localhost`, `192.168.x.x`). Both count within the same license. Public-facing servers each require their own license. *** ## Usage **Does eTools support Folia?** Yes. eTools natively uses Folia region schedulers for all area-breaking operations, tree felling, and utility item handling. **Can players use area tools on player-placed blocks?** By default, yes. Players can enable **Natural Only** mode via `/etools settings` to restrict area mining to naturally generated blocks. Admins can enforce this globally in `config.yml`. **How does the lifespan system work?** Each tool has a configurable expiry mode: * `ONLINE_TIME` - counts down only while the player is connected. * `REAL_TIME` - counts down in real-world time regardless of login status. * `UNLIMITED` - the tool never expires. Remaining time is stored per-item in the database and displayed in the item lore. **What happens when a tool expires?** Expired tools are removed from the player's inventory and any containers they are stored in. The plugin checks for expired items on startup and periodically during runtime. **Can I create my own custom tools?** Yes. All tools are defined in `plugins/eTools/tools.yml`. You can configure area dimensions (`width`, `height`, `depth`), lifespan, display name, lore, particles, sounds, enchantments, and more. See the [Custom Tools Guide](/docs/etools/core-features-and-mechanics/custom-tools-guide.md) for the full reference. *** ## Refunds & Support **Can I get a refund?** No. Because eTools is an intangible digital software product delivered immediately upon payment with a unique license key, all sales are strictly final and non-refundable. Please review our documentation and feel free to ask questions in our Discord server before purchasing. See the [Terms of Service](/docs/etools/legal/terms-of-service.md) for full details. **Where do I get support?** All support is handled through the EproMC Discord server. Open a ticket and include your license information and any relevant error logs from your server console. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://epromc.gitbook.io/docs/etools/legal/faq.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
