GrowMaster does not collect, store, transmit, or share any personal information or grow data. All data you enter into the application (strains, feeding schedules, journal entries, grow parameters, etc.) is stored exclusively on your local device using browser local storage.
When you purchase a license, Square handles card payments and NOWPayments handles crypto. We receive your email and order details so we can send your unlock code. We never see your full card number.
The only information we receive is your email address and license key for purchase fulfillment. We use this solely to:
We do not use cookies. The only local storage used is browser localStorage on YOUR device, which we use to store your license key verification and app preferences.
We use Square for card payments and NOWPayments for cryptocurrency. Their privacy policies apply to those checkouts. See squareup.com/legal/privacy and nowpayments.io/privacy-policy.
Since we don't store your data on our servers, there is no risk of data breach on our end. Your grow data remains entirely on your device. We recommend regular backups of your device and exporting your journal entries using the app's built-in export feature.
GrowMaster is not intended for users under the age of 18. We do not knowingly collect information from minors.
GrowMaster is designed for legal growers. It is your responsibility to ensure compliance with local laws regarding cannabis cultivation in your jurisdiction.
Since we don't collect your data, there is nothing to delete, export, or correct. Your data is yours and remains on your device. You can clear all app data at any time by clearing your browser's local storage.
If we make changes to this privacy policy, we will update the "Last updated" date. Continued use of GrowMaster after changes constitutes acceptance of the updated policy.
