Welcome to MustStash! We're dedicated to transforming the art of cardmaking by simplifying how you organize and find your crafting supplies. This Privacy Policy (“Policy”) is issued by MustStash, LLC ("we," "us," or "MustStash"), and it outlines how we collect, use, and protect your personal data across our platforms, including the MustStash mobile and web applications (the "App") and our website (muststash.io).
Here at MustStash, we understand that your creative journey is more than just a hobby, it's a passion that connects you with a community of fellow crafters. That's why safeguarding your personal information is a priority for us, ensuring that your privacy is respected and protected in accordance with applicable data protection laws and regulations.
By using our services, you agree to the practices described in this Privacy Policy. If you have any questions or concerns about how we handle your data, please contact us at support@muststash.io.
We take your privacy seriously. MustStash is committed to handling your personal information responsibly, securely, and in compliance with applicable data protection laws, including the principles of privacy by design. This means that we build our services with privacy in mind from the start and continually review our practices to protect your information and respect your rights.
This policy applies to all information collected through the MustStash mobile and web applications, our website (muststash.io), and any other direct interactions you may have with MustStash in connection with your personal use of our services.
By accessing and using the MustStash mobile or web applications and our website (muststash.io), you acknowledge that you have read and understand this Privacy Policy and agree to be bound by its terms. If you do not agree with the terms of this Policy, please discontinue use of our products and services.
The MustStash app and website are intended for users who are 13 years of age or older.
We collect limited technical data to maintain and improve our services:
We currently do not use crash logging or in-app analytics tools.
Third-Party Content: Some parts of the app may display embedded content (such as YouTube videos). When you interact with this content, the third-party provider may collect information such as device identifiers or usage data, in accordance with their own privacy policies. We do not control or manage the data practices of these third parties.
Access to Stash Data: Your personal crafting stash data, including items you have added and projects you have created, is accessible to you through our app. Currently, we do not offer a feature to export this data outside of the app. If we add an export feature in the future, we will update this Privacy Policy and notify you.
App Functionality: We use your information to ensure the smooth functioning of the app. This includes maintaining your user profile, managing your stash, wishlist, and projects, and facilitating your interaction with the app. Address information you may provide in your profile is currently stored but not used for any active features.
App Updates and News: We may use your contact information (such as your email address) to inform you about important updates to the app, including new features or changes to our services.
We do not currently send personalized push notifications. If we introduce notification features in the future, we will update this Privacy Policy and provide options for you to manage your preferences.
We do not currently use your personal information for targeted marketing or promotional purposes beyond general app-related updates and crafting news.
If we introduce marketing or promotional features in the future (for example, suggestions based on your stash data), we will ask for your explicit consent first. You will always have clear options to opt in or opt out of these communications.
Any future marketing activities will be conducted with full transparency, ensuring your choices are respected and that you only receive the content you choose.
We are committed to protecting the confidentiality, integrity, and availability of your personal data. We use a combination of physical, administrative, and technical measures designed to prevent unauthorized access and misuse of your information. These measures include, but are not limited to:
Despite our best efforts, no method of transmission over the Internet or method of electronic storage is completely secure. However, we have procedures in place to address any suspected personal data breach and will comply with all applicable laws regarding breach notifications.
Breach Notification: In the event of a data breach, we will promptly notify you of any unauthorized access to your personal data that could result in serious harm.
Incident Response: We maintain internal procedures to guide our response in the event of a data breach or other security incident.
We build MustStash with privacy in mind from the start. This means we limit the personal data we collect, provide user-friendly settings where possible, and review our features to make sure your information is protected by default throughout its lifecycle.
We do not currently share your personal data with third parties for marketing or analytics purposes. In the future, we may introduce optional features (such as content creator or company accounts) that use aggregated, anonymized data to provide insights about trends in the crafting community. If we add such features, we will update this Privacy Policy and clearly explain how your information is used.
We respect the privacy of our users. We do not sell your personal data or share it with third parties for advertising purposes.
We comply with legal requirements for data disclosure. If we are required by law to disclose your information, we will do so only to the extent necessary and with careful consideration of your privacy rights.
Internally, we may use data to operate and improve our services, enhance your experience, and better understand how our app is used. Any analysis is focused on improving the service and not on selling or advertising your personal information.
We use trusted third-party service providers to help us operate MustStash. These services may include hosting, data storage, communication, and other technical support. Some features may also display embedded third-party content (such as YouTube videos). When you interact with this content, the third-party provider may collect information in accordance with their own privacy policies.
All third-party providers we use are selected for their strong security practices and are only permitted to process personal data on our behalf, in accordance with this Privacy Policy and applicable laws.
Our commitment to data security involves employing industry-standard measures to help safeguard data against unauthorized access, disclosure, alteration, and destruction. We regularly review and update our security protocols to maintain a strong level of protection.
Please be aware that no method of electronic storage or transmission over the Internet is entirely secure. While we strive to use the best available means to protect your data, absolute security cannot be guaranteed.
User Responsibility: We encourage you to take steps to protect your account, such as using a strong password and keeping your login credentials confidential. If you suspect that your account has been compromised, please contact us immediately.
At MustStash, we understand that your needs may change over time. This section explains how you can manage your account, including options for cancellation and what happens to your data if you decide to deactivate or delete your account.
Delete Account (Inactive State): If you choose “Delete Account” in your account settings, your account will be marked as deleted and placed in an inactive state. Your data — including your stash, wishlist, and project details — is preserved but not accessible to you or others. This allows you to reactivate your account later without having to re-enter your information.
Permanent Account Deletion: If you wish to permanently delete your account and remove all associated data from our servers, you may contact us at support@muststash.io. We will process your request promptly and confirm the deletion. Once completed, your data cannot be recovered, and you would need to create a new account if you return to MustStash in the future.
You have the right to access the information we hold about you. Much of your information can be viewed and updated directly within the app, such as your stash, wishlist, projects, and profile details. If you find that other account information is inaccurate or incomplete, you may contact us at support@muststash.io to request updates or corrections. We strive to maintain accurate and up-to-date records to enhance your experience with our service.
We respect your choices about how you receive updates from us. At this time, communications are limited to email, and you may unsubscribe from non-essential emails by following the instructions included in those messages. If we introduce additional notification options in the future (such as in-app or push notifications), we will update this Privacy Policy and provide you with clear ways to manage your preferences.
We currently retain user data indefinitely, since many users may wish to reactivate their accounts in the future and prefer to have their stash, wishlist, and project details preserved. Data for inactive accounts is stored securely and remains accessible only as necessary for the provision of our services or as required by law.
If you wish to have your data permanently deleted, you may request this at any time (see Section 10.1). Once completed, permanent deletion cannot be reversed.
Should our data retention policies change in the future — for example, if we begin automatically deleting dormant accounts after a certain period — we will notify users in advance. Any modifications to our data retention practices will balance user convenience with legal obligations, and we will continue to handle your data with care and respect for your privacy.
If you are a resident of the European Union or California, you have specific rights under the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA). These include the right to request access to, correction of, or deletion of your personal data, as well as the right to request a copy of your data be transferred to another organization. To exercise these rights, please contact us at support@muststash.io. We are committed to facilitating your requests in accordance with applicable law.
Residents of other regions may have similar rights under their local laws, and we will honor those rights where applicable.
At MustStash, cookies are only used on our public website (muststash.io), not in the MustStash app. We use a limited number of cookies and tracking technologies, primarily through Google Analytics, to understand visitor interactions on our website. This information helps us improve and optimize your experience on the site.
We do not use cookies for targeted advertising or extensive tracking beyond our website. You can manage or disable cookies through your browser settings, although some features of the site may not function properly without them.
You can control how cookies are used through your browser settings. Disabling cookies may limit certain website features. If we introduce additional tracking methods in the future, this Privacy Policy will be updated and users will be notified.
We are committed to maintaining transparency with our users. As our services evolve and as legal or business requirements change, updates to this Privacy Policy may become necessary. When that happens, we will communicate those changes clearly so you understand how your information is being handled.
Any significant changes to this Privacy Policy will be communicated through prominent notifications on our website or by email. We encourage you to periodically review the Privacy Policy to stay informed about how we protect your personal information.
By continuing to use our services after changes to this Privacy Policy, you signify your acceptance of the updated terms. If you do not agree with the changes, you may discontinue use of our services. You also have the option to delete your account at any time through the app settings, or to request permanent deletion of your account and data by contacting us at support@muststash.io.
We value your feedback and are committed to addressing your questions and concerns. If you have concerns about how your data is being used or questions about your rights, please contact us at support@muststash.io or through the Contact Us form on our website.
