| Data use | Cinch says it does not sell, rent, or share personal information or Google Calendar data with third parties, and does not use calendar data for advertising or unrelated purposes. | Sylly says it does not sell, rent or trade personal information and does not use advertising cookies or third-party marketing trackers. |
| Purpose | Cinch is a mobile study planner for college and graduate students. | Sylly describes itself as an all-in-one AI study app for university and college students; uploading a syllabus lets it build a semester plan. |
| Security | Cinch says device-to-server and server-to-Google communications use TLS/HTTPS, JWTs handle sessions, and Google OAuth tokens are encrypted in its database rather than stored in plain text. | Sylly lists TLS/HTTPS encryption, bcrypt password hashing, row-level database security, secure HTTP-only cookies and rate limiting among its security measures. |
| Support | The App Store listing provides [email protected] for questions. | Sylly says support is available by email and typically replies within a few business days. |
