Does GrowScope Share or Sell My Grow Data?
No. GrowScope doesn't sell grow-diary data, doesn't run ad trackers that would make that data valuable to sell, and — since diary content is encrypted end-to-end on every account — doesn't have readable data to share even if it wanted to.
No ad trackers, no analytics resale
GrowScope doesn't use Google Analytics, third-party ad trackers, or crash reporters that phone data out to another company. Whatever private, first-party analytics exist are used to run the product, not sold or shared with advertisers — there's no data broker relationship generating revenue from your grow logs.
Signup doesn't create much to share in the first place
An account is just a username, no password — no email, phone number, or real name is requested or stored either, and the account ID is a random number with no link to any personal identity. There's very little personally identifying information sitting in the database to begin with, encryption aside.
Diary content is encrypted, which makes the question moot for the content that matters most
Even setting policy aside: plant records, logs, and notes are encrypted end-to-end, so the server only holds unreadable bytes for that content. There's no readable grow diary sitting in a database that could be shared, sold, or handed over on request, because no one but the account holder has the key to read it.
Anonymous benchmarks are the one place data leaves your account — depersonalized
The one feature that compares data across users is Grower Benchmarks, and it's built to be structurally disconnected from accounts: what's published is a cycle length, a day number, a development score or yield figure, and a place type — never a name, user ID, photo, or analysis text. It's opt-in by nature of using the feature, and there's no version of it that reveals whose data it is.
How GrowScope helps
You can see and verify all of this yourself: everything can be exported or erased from Settings at any time, and the full technical detail behind both the encryption and the anonymous-benchmark design is documented rather than just asserted — see the Encryption and Account & Data Privacy documentation.
Key takeaway
GrowScope doesn't sell data or run ad trackers, doesn't collect much personal information at signup to begin with, and diary content is encrypted end-to-end — so there's no readable grow journal sitting anywhere that could be shared or sold, even internally.
