CardWarden CardWarden

Terms of Use

CardWarden Mobile App

Effective Date: August 19, 2026

1. Acceptance of Terms

By downloading, installing, accessing, or using the CardWarden mobile application ("the App"), you agree to be bound by these Terms of Use ("Terms"). If you do not agree to these Terms, do not use the App.

You must be at least 13 years of age to use the full features of the App, including offline mode and account creation. By proceeding past the age verification screen in the App, you confirm that you are 13 years of age or older.

Children under the age of 13 may use the App only in Kids Mode. Kids Mode is designed for families with children to have peace of mind: a parent or guardian with a CardWarden account can invite a child to join their family using the "Add a child" feature, without the child needing to create an account of their own. In Kids Mode, the child has read-only access to cards that have been explicitly shared with them and nothing else — they can view those cards and update their balances, but cannot see any other cards, pockets, or account data, and cannot create their own account, pockets, or cards.

If you are a parent or guardian inviting a child under 13 to use Kids Mode, you represent that you have the legal authority to consent on behalf of the child and that you accept these Terms on their behalf.

2. Description of Service

CardWarden is a mobile application that helps you securely store and organize cards such as loyalty cards, gift cards, credit cards, debit cards, and membership cards. The App operates fully offline on your device. You may optionally create an account to access cloud features including backup, multi-device sync, and family sharing.

CardWarden is built on a zero-knowledge encryption model. Your sensitive card data is encrypted on your device before it is transmitted to our servers. We do not have access to your unencrypted data at any time.

3. Account Registration

Certain features of the App require you to create an account. When you register, you agree to:

  • Provide accurate and complete information.
  • Maintain and promptly update your account information to keep it current.
  • Not share your login credentials with any other person. A single account may not be shared by multiple people.
  • Promptly notify us at support@cardwarden.app if you become aware of any unauthorized use of your account.

You are responsible for all activity that occurs under your account, whether or not you authorized it.

4. Zero-Knowledge Architecture and Data Responsibility

CardWarden uses a zero-knowledge encryption architecture. This means:

  • Your master password never leaves your device. It is used to derive the encryption keys that protect your data. We never receive, store, or have access to your master password.
  • We cannot access your encrypted data. The data stored on our servers is encrypted and cannot be read by anyone without your master password, including us.
  • We cannot recover your data. If you lose both your master password and your 12-word recovery phrase, your encrypted data becomes permanently inaccessible. We have no ability to reset your master password, decrypt your data, or restore access to your account on your behalf.

You acknowledge and accept that the security of your data depends entirely on your safekeeping of your master password and recovery phrase. thesimplest.net shall not be liable for any data loss, inability to access your account, or any other consequence resulting from your loss of these credentials.

5. Your Security Responsibilities

Because CardWarden is a security application that protects sensitive information, you play a critical role in keeping your data safe. You are solely responsible for the following:

Credentials and Recovery

  • Choosing a strong, unique master password that is not reused on any other application, website, or service.
  • Safeguarding your 12-word recovery phrase by storing it securely offline (for example, written on paper in a safe location). Storing the recovery phrase in digital form — such as in a notes app, email, cloud storage, or messaging app — increases the risk of it being compromised, and any resulting data loss is your responsibility.
  • Not sharing your master password, recovery phrase, or account credentials with any other person.

Device and Environment Security

  • Securing your device with a strong screen lock (PIN, password, pattern, or biometric) and not leaving your device unattended while unlocked.
  • Not using the App on devices that have been rooted, jailbroken, or otherwise modified in ways that may compromise the device's security protections, including the hardware keystore or secure enclave.
  • Not using the App on shared or public devices, such as those found in internet cafes, libraries, or shared workspaces, where others may have access to the device.
  • Not granting accessibility, screen-reading, or overlay permissions to untrusted applications that could capture card data displayed on screen.
  • Keeping your device operating system and the App updated to the latest available versions to ensure you receive the latest security patches and improvements.

Network and Public WiFi Safety

  • Exercising extra caution when using the App on unsecured, shared, or public WiFi networks, including networks at airports, hotels, cafes, shopping centers, schools, workplaces, and public transport locations.
  • Avoiding account sign-in, password changes, recovery actions, sharing, exports, or other sensitive actions while connected to public WiFi unless reasonably necessary.
  • Using a reputable VPN when you must use public WiFi, and disconnecting from the network when you no longer need it.
  • Confirming that your device is connected to the network you intended to use, and avoiding unknown or suspicious WiFi networks that may imitate legitimate public networks.
  • Disabling automatic connection to open WiFi networks where possible and forgetting public networks after use.
  • Not accepting unexpected certificate, security, login, or browser warnings while using the App or accessing related account services.

App Security Settings

  • Enabling the security features available in the App, such as biometric unlock, app lock PIN, and an appropriate lock timeout setting.
  • Not manually taking screenshots or screen recordings of sensitive card data displayed in the App. Screenshots and recordings are stored outside of the App's encrypted protection and may be automatically backed up to cloud services, synced across devices, or accessible by other applications.
  • Not photographing the App screen with another device. Such photographs are entirely outside of CardWarden's control and protection, and could be inadvertently shared or accessed by others.

Sharing and Export

  • Using strong, unique passphrases when sharing cards via encrypted share links.
  • Not posting or transmitting card share links or QR codes through public or semi-public channels (such as social media, public forums, or large group chats) where unintended recipients could access them.
  • Revoking shared access from family pocket members who should no longer have access.
  • Securing any data files you export from the App (such as spreadsheet exports), storing them in a protected location, and deleting them when no longer needed. Exported files are not encrypted by CardWarden and are your responsibility to protect.

Account Hygiene

  • Removing or deauthorizing devices from your account after loss, sale, or transfer of the device.
  • Being vigilant against phishing attempts that impersonate CardWarden in order to capture your master password or other credentials.
  • Promptly notifying us of any suspected unauthorized access to your account.

You acknowledge that any financial loss, personal loss, data exposure, or data loss resulting from your failure to follow these security responsibilities is solely your responsibility. thesimplest.net shall not be liable for any damages arising from your negligence in securing your account, device, credentials, or data.

6. Subscriptions and Payments

CardWarden offers optional paid plans that unlock additional features. Premium Cloud and Premium Family are auto-renewable subscriptions. Premium Offline is a one-time (non-subscription) purchase. All purchases and payments are processed through the platform store (Apple App Store or Google Play Store) through which you downloaded the App. thesimplest.net does not collect, process, or store your payment details such as credit card numbers or billing addresses.

6.1 Auto-Renewable Subscriptions

The following auto-renewable subscriptions may be offered in the App:

  • Premium Cloud (Monthly) — billed every 1 month. Includes encrypted cloud backup, multi-device sync, and related Premium Cloud features for an individual account for the duration of each subscription period.
  • Premium Cloud (Yearly) — billed every 1 year. Includes the same Premium Cloud features for each yearly subscription period. A free trial may be offered where available and where you are eligible.
  • Premium Family (Monthly) — billed every 1 month. Includes everything in Premium Cloud for up to five family seats, shared pockets, role-based access, and related Family features for the duration of each subscription period.
  • Premium Family (Yearly) — billed every 1 year. Includes the same Premium Family features for each yearly subscription period. A free trial may be offered where available and where you are eligible.

The price of each subscription, including any applicable taxes, is shown in the App and confirmed by Apple or Google before you purchase. Prices may vary by storefront, currency, and region, and may change over time.

6.2 Auto-Renewal, Billing, and Cancellation (Apple App Store)

If you purchase an auto-renewable subscription through the Apple App Store:

  • Payment will be charged to your Apple ID / App Store account at confirmation of purchase, or at the end of any applicable free trial if you do not cancel before the trial ends.
  • Your subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current subscription period.
  • Your account will be charged for renewal within 24 hours prior to the end of the current period, at the renewal price identified for that subscription.
  • You may manage your subscription and turn off auto-renewal at any time in your Apple ID Account Settings after purchase (for example, Settings > [your name] > Subscriptions on iOS), or via the App Store subscription management page.
  • Any unused portion of a free trial period, if offered, will be forfeited when you purchase a subscription to that service, where applicable.
  • Deleting the App or your CardWarden account does not by itself cancel your subscription. You must cancel through Apple’s subscription settings to stop renewal.

6.3 Google Play and General Payment Terms

  • If you purchase through Google Play, subscription pricing, billing cycles, renewal, and cancellation are governed by Google Play’s policies and managed in your Google Play account settings.
  • Refund requests are handled exclusively by the platform store (Apple or Google) in accordance with their refund policies. thesimplest.net does not process payments or issue refunds directly.
  • Subscription prices are subject to change. If the price of an auto-renewable subscription increases, Apple or Google will notify you as required, and the new price will apply according to the applicable store’s rules (typically at the start of the next billing period after you accept, or as otherwise required by store policy).
  • Your Privacy Policy is available at cardwarden.app/privacy-policy. These Terms of Use (EULA) are available at cardwarden.app/terms. Both links are also accessible from within the App.

The foregoing limitations will apply even if any remedy fails of its essential purpose. This limitation of liability applies to the fullest extent permitted by law in the applicable jurisdiction.
