Privacy Policy

Your data, explained clearly.

Last updated September 28, 2026

Privacy at a glance

This policy explains how MSTools handles information in the iPhone app, on mstools.dev, and through api.mstools.dev. Contact the MSTools developer at support@mstools.dev with privacy questions or requests.

You do not need an MSTools account or a MapleStory login. We do not ask for your MapleStory password. We do not sell personal information, use advertising SDKs, or track you across other companies’ apps and websites.

What stays on your device

The app saves your character library and snapshots, selected chart period, equipment setups, flame inputs and calculated results on your device. Avatar images are cached locally. Equipment artwork and calculator data are bundled with the app.

MSTools does not upload your equipment setups or flame calculations to its servers. Device backups managed by Apple may include app data, depending on your backup settings. MSTools does not provide its own cloud backup or cross-device sync for these records.

Character lookups and technical information

When you search for or refresh a character, the app sends the character name and, when needed, region to the MSTools API. Avatar requests include a character identifier and image version. The API returns public MapleStory ranking information, including character name, job, world, level, EXP history, rankings, and avatar information. A lookup does not establish that you own that character.

Our website and API are hosted by Cloudflare. Network requests expose technical information such as IP address, request URL (which can contain a character name), request time, browser or app information, and response status to the hosting infrastructure. Operational logs and security services may process this information to deliver content, diagnose problems, and protect the service.

Avatars are normally served from our cache. When an avatar is not available there, the API can redirect your device to Nexon’s image service. Nexon then receives the network information needed to deliver the image.

Purchases and support

Apple processes subscriptions, one-time purchases, payments, and refunds. The app uses Apple’s StoreKit to check verified purchase records and determine Premium access. We do not receive your payment card details, and the app does not send purchase records to an MSTools account server.

If you email support, we receive your email address, message, and any attachments you choose to send. We use them to respond and resolve your request. Please do not send passwords or payment card details.

How information is used and shared

We use information to provide character data, save your preferences locally, verify access to paid tools, respond to support, maintain security, and meet legal obligations. Cloudflare provides hosting and infrastructure; Apple provides purchases and device services; our email provider processes support correspondence. Nexon may serve avatar images as described above.

We may disclose information when required by law or reasonably necessary to protect users, enforce our terms, or address fraud and security incidents. We do not share information for targeted advertising. The website does not add analytics scripts or advertising cookies; infrastructure providers may process technical data for delivery and security.

These providers may process data outside your country. Their services are also subject to their own policies, including Cloudflare’s Privacy Policy and Apple’s Privacy Policy.

Retention and deletion

Local records remain until you remove them in the app or delete the app’s data. Deleting the app, rather than offloading it, removes its local data; copies in device backups are managed through your Apple settings. Cached images may be replaced or removed by the app or operating system.

Public ranking records are maintained separately from your saved character library. Removing a saved character does not remove its public ranking data from our service or Nexon’s rankings. Ranking records and server-side avatar caches are retained to provide character history and lookup functionality, and may be refreshed or removed as the dataset changes.

Technical logs follow our hosting provider’s applicable retention settings. Support messages are retained for as long as needed to resolve and follow up on the request, comply with legal obligations, and handle disputes. We do not promise immediate removal from provider backups or records that must be retained by law.

Your choices and rights

You can remove saved characters and equipment setups in the app, manage device backups through Apple, and manage purchases in your App Store account. There is no MSTools account to delete. To request access, correction, deletion, or information about data handled by MSTools, email support@mstools.dev. Include enough detail to identify your request without sending unnecessary sensitive information.

Depending on where you live, you may also have rights to portability, restriction, objection, withdrawal of consent where processing relies on consent, or a complaint to your local data protection authority. We may need to verify your request and will handle it subject to applicable law. We cannot delete information held independently by Apple or Nexon on their behalf.

Children and security

MSTools is a general-audience game companion and is not directed to children under 13. If you believe a child has provided personal information to us, contact support so we can investigate and address it.

We use HTTPS for our website and API and rely on platform protections for local app storage. No storage or transmission system is completely secure.

Policy updates

We may update this policy as the app or our practices change. The latest version will be available on this page with a revised date. We will provide additional notice or seek consent when required by applicable law.
