# SightRadar FAQ

> Plain answers about migrating from AWS Rekognition, what a faceprint is, whether data is used for training, pricing, and GDPR/BIPA posture.

**Is SightRadar really compatible with AWS Rekognition?**
Yes. The face operations use the same request/response shapes (CreateCollection, IndexFaces, SearchFacesByImage, SearchFaces, CompareFaces, DetectFaces, ListFaces/DeleteFaces, ListCollections/DeleteCollection). Point your SDK at `https://api.sightradar.com` and use a SightRadar key. A Python shim maps Rekognition method names.

**How much does it cost?**
Per photo processed, in USD: real-time index $0.00093, batch index $0.00062, search $0.00062, storage $6/million faces/month. Prepaid credits, no subscription. See https://sightradar.com/pricing.

**Am I billed per face or per photo?**
Per photo processed. A photo with zero faces is a valid, charged, successful result. A selfie that fails the quality gate on search returns a clear reason with an empty match list and is not charged for the failed engine call.

**What is a faceprint / embedding?**
A numeric vector derived from a face, used to measure similarity. SightRadar stores embeddings in per-tenant collections that are never cross-searchable; Detect and Compare process images in memory and don't persist them. See https://sightradar.com/glossary.

**Do you train models on my data?**
No. Data is processed only to return your results — never pooled, never used to train general-purpose models, never sold.

**What about GDPR / BIPA?**
The customer is the data controller and is responsible for a lawful basis and consent. Data is encrypted in transit with per-tenant isolation and scoped keys, and faces can be deleted any time via API or console. See https://sightradar.com/trust and https://sightradar.com/privacy.

**Can I avoid running out of credits mid-batch?**
Yes — optional auto-recharge tops up your wallet before a batch drains it, and every billable call returns an `X-Credits-Remaining` header.
