Frequently Asked Questions
- Does Sievr upload my photos anywhere?
- No. Sievr processes everything entirely on your device using Apple's Vision framework and Foundation Models. No photos, thumbnails, or image data are ever uploaded, transmitted, or shared. We have no servers to receive them.
- Why does Sievr need full photo library access?
- To scan your entire library for similar and duplicate photos, Sievr needs to analyze all your photos — not just a selected few. Limited access would only let the app see photos you manually pick, making automatic scanning impossible. Sievr only reads your photos for analysis; it never copies or stores the actual image data.
- What happens when I delete photos through Sievr?
- Photos deleted through Sievr are moved to your Recently Deleted album in the Photos app, where they remain recoverable for 30 days. Sievr never permanently deletes photos. You can recover any photo within that 30-day window through the Photos app.
- How does the quality scoring work?
- Sievr evaluates each photo across multiple factors: sharpness and focus, aesthetic composition, face quality (for photos with people), and lens clarity. Each factor contributes to an overall quality score. When available, Sievr uses on-device AI to explain in plain language why one photo scored higher than another.
- What is the difference between free and paid?
- The free version lets you scan your entire library, see all quality scores and similarity groups, and delete up to 50 photos per month. The one-time $4.99 upgrade unlocks unlimited deletions, bulk cleanup, and cleanup reports. There are no subscriptions.
- Does Sievr work without an internet connection?
- Yes. All scanning, scoring, and cleanup features work entirely offline. Sievr makes no network requests.
- What data does Sievr store?
- Sievr stores only scan metadata: references to your photos (not copies), quality scores, and similarity groupings. This data is stored locally on your device using Apple's SwiftData framework. No actual photo data is ever copied or stored by Sievr.
- What happens to my data if I delete the app?
- All Sievr data is stored locally on your device. When you delete the app, all associated scan data is permanently removed by iOS. Your photos remain untouched in your Photos library. There is nothing to delete from any server because no data is ever transmitted off your device.
- What iOS version is required?
- Sievr requires iOS 26 or later and is designed for iPhone.
- Does Sievr support RAW photos?
- Yes. Sievr works with all photo formats supported by your iPhone, including HEIF, JPEG, PNG, and RAW.
