No. All browsing, similarity detection and compression happen on your device. Nothing is uploaded to our servers. See the Privacy Policy.

SortFolio does not permanently delete photos immediately. They are moved to iOS's "Recently Deleted" album, where iOS keeps them for 30 days. You can recover them from there during this period; after 30 days iOS automatically purges them.

Free users can organize up to 50 photos per day. The quota resets daily at midnight. To remove the quota, subscribe to or purchase Pro from Settings → Upgrade Pro.

SortFolio promo codes are issued through Apple's standard channel (Promo Codes / Offer Codes generated in App Store Connect). On iPhone there are two ways to redeem:

Option 1: Inside SortFolio

1. Open SortFolio → Settings → tap "Upgrade Pro" to open the paywall
2. Scroll to the bottom of the paywall and tap "Redeem Promo Code"
3. Enter the code in the Apple redemption sheet that appears and confirm

Option 2: In the App Store

1. Open the App Store → tap your avatar in the top-right corner
2. Choose "Redeem Gift Card or Code"
3. Enter the code and confirm

Once redeemed, return to SortFolio and your Pro status will sync automatically. If it doesn't take effect, tap "Restore Purchases" at the bottom of the paywall. If you see "Invalid code", check for stray spaces or letter case, or email us to verify.

No. Sign in with the same Apple ID on the new device → open SortFolio → open the paywall → tap "Restore Purchases". Whether you subscribed, bought the lifetime tier, or activated via an Apple promo code, your entitlement is tied to your Apple ID and is restored by the App Store automatically. Email us if it doesn't restore.

Subscriptions are managed by Apple. Go to:
iPhone Settings → your name at the top → Subscriptions → SortFolio → Cancel Subscription.
You'll keep Pro access until the current period ends.

No. SortFolio only reads from the iOS Photos library and does not keep its own copies. Any change you make on the system side (empty / restore) is automatically reflected.

Currently, SortFolio's "organized records" and "aesthetic score cache" are stored locally on each device and do not sync across devices. The Photos library itself syncs via iCloud Photos if you have it enabled.

Detection runs entirely on-device: similarity uses perceptual hashing plus a time window; aesthetic scoring uses a local NIMA model. We keep improving accuracy, but mistakes can still happen — please review before deleting.

Yes. SortFolio's photo and video compression is lossy by design — the goal is significant size reduction, and the process is not reversible. Please make sure originals are backed up to iCloud or elsewhere before compressing. The app shows reminders on the compression screen.

1. Swipe the app away to close it, then relaunch
2. Restart your iPhone
3. Check the App Store for an update
4. If the issue persists, email us with your device model, iOS version and SortFolio version

App Store reviews are very helpful for an independent developer. For specific feature requests or bug reports, email is the most reliable channel.

SortFolio does not collect personal information. Pro activation only uses an anonymous device identifier. To request deletion of any activation records on our server, email us — we'll process within 30 days. See the Privacy Policy.
