Question 1

How does the face matching actually work?

Accepted Answer

We compute a 128-dimensional embedding from a guest's selfie on their device. That embedding is compared with the face index we build from your uploaded photos. Only the embedding leaves the device — never the raw selfie.

Question 2

How accurate is it?

Accepted Answer

98% top-1 accuracy on real wedding datasets, even with low light, makeup, sunglasses and partial occlusion. Edge cases are flagged so you can manually curate.

Question 3

Which languages do you support?

Accepted Answer

French, Arabic (with full RTL) and English. The guest experience auto-detects the system language.

Question 4

How do I pay?

Accepted Answer

WhatsApp payment with manual confirmation for now. Bank transfer, Baridi Mob and CCP all accepted. Card/Stripe coming Q3 2026.

Question 5

Can I use my own watermark?

Accepted Answer

Yes. Upload your watermark once in Settings and Lumas applies it to every gallery preview. Originals are delivered unwatermarked on download.

Question 6

What happens to my photos if I cancel?

Accepted Answer

You have 90 days to export everything. After that, we delete embeddings and originals. Guests retain links unless you revoke them.

Question 7

What are the pricing plans and currencies?

Accepted Answer

We offer three plans in two regions. For Algeria (DZD): Basic at 2,900 DA/month, Pro at 7,900 DA/month, Business at 19,900 DA/month. For international photographers (USD): Basic at $19/month, Pro at $49/month, Business at $129/month. All plans include a 1-event free trial — no card required.

Question 8

How long do you keep my photos?

Accepted Answer

Photos are stored for the duration of your active subscription. If you cancel, you have 90 days to export everything before deletion. Business plan includes a 12-month cold-storage archive option. You can also trigger immediate deletion from Event Settings at any time.

Question 9

How do I request deletion of my face data?

Accepted Answer

Guests can request deletion by emailing privacy@lumasphoto.com with the event share code and their name. We delete all face embeddings and matched photo links within 48 hours and send a confirmation. Photographers can also bulk-delete all guest data for a closed event from the Studio dashboard.

Question 10

Is Lumas Photo GDPR / Algerian data-protection law compliant?

Accepted Answer

Yes. Face embeddings are processed server-side and never shared with third parties. Raw selfies are deleted after matching. All data is stored in EU-based Supabase infrastructure (Frankfurt). We are compliant with GDPR and the Algerian Law 18-07 on personal data protection. Our full Data Processing Agreement is available on request.
