Domain Due Diligence
Report for Keiki.app
Why we think so?
keiki.app shows many legitimate technical and traffic signals (AWS hosting, CDN, valid SSL, SPF/BIMI, and ~430k monthly visits with a US audience). The site publishes contact points (support@keiki.app) and active social profiles, and it appears in neutral/positive news coverage. However, multiple independent app-store reviews and user complaint threads report unexpected or repeated subscription charges and difficulty obtaining refunds. No Safe Browsing or crypto blacklist hits were found. Verdict: proceed with caution—the service looks operational and legitimate, but billing and refund problems are a persistent reputational risk.
Risk Insights
Billing complaints are the main risk
- Multiple app-store reviews independently describe unexpected charges and repeated billing after cancellation.
- If you are evaluating this app, verify your subscription state in the App/Play Store and keep receipts.
- Technical signals look legitimate, but reputational risk stems from payment handling.
Strong technical footprint
- AWS hosting, CloudFront, and standard payment processors are in use.
- TLS, SPF and BIMI records present, indicating domain control and email setup.
- No Safe Browsing or crypto blacklist detections were found.
Contradictory Signals
The operator appears to run a legitimate, widely used product, yet poor billing practices or app-store subscription flows are causing user-reported financial harm.
Signal A: High traffic and mainstream infrastructure
Signal B: Multiple user complaints about repeated/unexpected billing
Category Scores
Red Flags & Warnings
- Repeated user reports of unexpected or multiple subscription charges and difficulty obtaining refunds (App Store / Play Store reviews).
- WHOIS registry data is not present in the pulled record, which reduces certainty about historical ownership and domain age.
- A website-traffic-data endpoint returned an error / unavailable result, limiting cross-checks of traffic trends.
🔎 Detailed Checks & Analysis
Technical infrastructure and integrations
Score: 90/100
Technical infrastructure and integrations
"Presence of Amazon hosting, CloudFront, Route53 and payment gateways indicates an operator using mainstream, reputable infrastructure and standard integrations for monetization and analytics."
Reason: Site runs on AWS with CloudFront/S3, uses standard analytics and payment providers (Stripe, PayPal, Apple Pay), and exposes protection/verification headers and tags.
Traffic volume & engagement
Score: 80/100
Traffic volume & engagement
"Estimated monthly visits and country breakdown suggest real user activity and a primarily US audience, which supports credibility but should be cross-checked with store-download figures."
Reason: SimilarWeb reports ~430k monthly visits, a 39% US share, and typical engagement metrics that look consistent with an active consumer app.
Contactability and social presence
Score: 75/100
Contactability and social presence
"Having visible, consistent support channels and social accounts increases traceability and gives users routes to escalate billing or content issues."
Reason: A support email (support@keiki.app) and multiple official social profiles are publicly listed, enabling direct contact.
Billing & refund complaints
Score: 30/100
Billing & refund complaints
"Multiple independent user complaints about subscription charges and refund handling are a significant reputational issue and increase consumer risk even if the operator is otherwise legitimate."
Reason: App-store reviews and forum threads report unexpected charges, repeated billing after cancellation, and poor refund resolution.
Blacklist / malware / phishing checks
Score: 95/100
Blacklist / malware / phishing checks
"Absence of blacklist matches lowers the likelihood of active malware or phishing distribution tied to the domain in known threat feeds."
Reason: No matches found on Google Safe Browsing and no crypto-scam blacklist entries were detected in the scanned sources.
Trademark / brand impersonation
Score: 100/100
Trademark / brand impersonation
"No USPTO results for 'keiki.app' were found in the pulled data, but trademark status can vary by jurisdiction; further counsel may be needed for commercial use."
Reason: USPTO search returned no matching trademarks for the queried name, reducing immediate concerns about legal brand conflicts.
WHOIS and ownership transparency
Score: 40/100
WHOIS and ownership transparency
"DNS and TXT records show domain control and verification tokens, but missing WHOIS metadata reduces ability to confirm long-term ownership and historical changes."
Reason: WHOIS registry details were not present in the fetched record, limiting certainty about domain age and registrant identity.
