Terms of Use

The Ollo SDK is an early-access, experimental developer toolkit. By downloading or using it, you agree to these Terms of Use. If you disagree with any part, please do not use the SDK.

The SDK is in active development. Features may change, break or be removed. Performance and accuracy may vary between hardware and environments. We do not guarantee uninterrupted operation and the SDK is provided “as is” during this beta period.

You are granted a non-exclusive, revocable license to use the SDK for prototyping, development and testing.

You may not:

• Redistribute the SDK as your own,
• Reverse-engineer core models or internals,
• Use the SDK for harmful or deceptive applications.

Commercial use requires written approval.

Ollo SDK provides probabilistic gameplay-oriented behavioral signals derived from optical facial landmark estimation. These signals are heuristic in nature and are not medical, neurological, biometric or diagnostic measurements.

The SDK should not be used for health assessment, medical interpretation, identity verification or safety-critical decision-making.

Ollo SDK relies on real-time visual landmark estimation and confidence-based inference. Accuracy and reliability may degrade under certain environmental or behavioral conditions.

Visual occlusion

• Strong glasses glare or reflections
• Sunglasses or tinted lenses
• Hands, hair or objects obscuring the eyes

Motion & positioning

• Large pitch or yaw rotations
• Rapid head movement
• Motion blur or unstable camera positioning

Behavioral edge cases

• Prolonged squinting
• One-eye closure or winks
• Facial tics, spasms or atypical blink behavior

Environmental conditions

• Low-light environments
• Rapid lighting changes
• Strong backlighting

In these situations, confidence values and signal stability may degrade before outputs become unreliable or unavailable.

The SDK runs on-device. By default, it may send lightweight, anonymized telemetry in beta builds for the purpose of improving performance and signal accuracy.

What we collect:

• performance metrics (FPS, latency, load times)
• anonymous feature usage (integrations, config flags)
• error and crash diagnostics

What we do NOT collect:

• Camera frames, video or images
• Any identity-related or personal data
• Player data of any kind
• Blink or behavioral signals themselves

Opting out

Telemetry is optional. You can disable it at any time through the SDK config. Opting out does not affect SDK functionality.

All game data, player state and in-game logic are entirely your responsibility and ownership. We do not store or process player-facing data.

We may release updates or changes to the SDK. Some updates may be required to maintain compatibility.

You use the SDK at your own risk. We are not liable for any damage, issues or losses resulting from use or integration of the SDK.

The SDK may include or depend on third-party open-source components and other libraries. These components are licensed separately by their respective authors. Their original licenses and notices are included in the THIRD_PARTY_LICENSES file distributed with the SDK. Your use of these third-party components is subject to the terms of their respective licenses, which take precedence over any conflicting terms in this agreement.
