Glean's public privacy statement covers statutory rights, sharing categories and transfer safeguards well but says nothing about its actual AI product, since the statement expressly excludes the Solutions, and its website terms take a perpetual sublicensable licence in user submissions.

What Glean's privacy policy and terms of service say about your data

Perpetual content licence

The Website Terms grant Glean a "worldwide, non-exclusive, perpetual, irrevocable, royalty-free, fully paid, sublicensable and transferable license" over User Submissions. Nothing ties that licence to operating the service.

AI product is out of scope

The Privacy Statement states it "does not apply to your use of our products and services (collectively, 'Solutions')", so training use, opt-outs, tier differences, AI-interaction disclosure and AI-log retention are all silent.

Portability is EEA-only

"The right to data portability" appears only in the GDPR section covering the EEA, UK plus Switzerland. The CCPA list omits it, so users elsewhere are not offered it.

Retention factors are not minimization

The clause about considering "the nature and sensitivity of the information" governs how long data is kept, not how much is collected. No data minimization commitment appears in either document.

What the policy is silent or vague on

Not stated: keeping user inputs out of model training
Not stated: a way to opt out of training
Not stated: whether training use differs by plan
Not stated: your ownership of generated outputs
