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

Strong technical footprint
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

🔎 Detailed Checks & Analysis
Technical infrastructure and integrations
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
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
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
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
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
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
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.
