If you decide to cancel your subscription, you will maintain full access to all system features until the end of your current billing cycle.

Data Retention & Grace Period

• Access After Cancellation: Your service remains active until the official expiration date unless the cancellation is processed while the account is already expired.
• Data Safety: Once your subscription expires, your data is not immediately deleted. We provide a grace period to ensure your information remains secure while you decide on your next steps.
• Reactivation: To avoid data loss, please ensure you renew or export your data before the grace period ends.

For detailed information regarding expired subscriptions and recovery, please visit our Subscription Expiration Policy.

If your subscription has expired, your data is safe. You will be able to access all your information immediately once you successfully renew your account.

How long is my data stored?

We understand that you may not be able to renew right away. To provide you with flexibility, we adhere to the following retention policy:

• 6-Month Grace Period: We keep your data secure for 6 months from the date your subscription expires and your account becomes inactive.
• Data Deletion: If the account remains inactive after 6 months, all associated data will be permanently deleted from our systems.

Deletion Notifications

We won’t delete your data without warning. You will receive an email reminder one month before the scheduled deletion, giving you ample time to reactivate your account and preserve your information.

Summary Table

Settings are the backbone of the WRSMS platform. They allow you to define global defaults—such as order types, payment methods, and standard rates (pickup vs. delivery). Proper configuration is essential; without these settings, the system cannot function accurately.

By optimizing your settings, you can significantly reduce manual data entry. For instance, when creating a new sales record, the form can auto-populate with your preferred order type, saving time and reducing the risk of human error during busy hours.

Beyond transaction defaults, the Settings module also enables the system to: * Monitor Inventory Levels: Track gallon counts and consumables in real-time. * Manage Backwash Schedules: Ensure equipment maintenance is performed on time to maintain water quality.
