Swing Level Up Terms of Use
Effective date: October 11, 2026
1. Purpose
These Terms set out the conditions, rights and duties for using the tennis app "Swing Level Up" for iOS, Android and Apple Watch (the "App") and related services (the "Service") provided by INXIGHT ("we").
2. What the Service is — we are not a party to your games or deals
2.1 The Service is a platform where members post, find and talk to each other. It offers posts for games, lessons, guest spots and events, partner and dating introductions, chat, the Market, a scoreboard, records, clubs and court information.
2.2 Games, lessons, court bookings, events and item trades are arranged directly between members. We do not run games, lessons or courts, and we are not a party to any agreement or trade between members.
2.3 We do not receive, hold or transfer money between members (court fees, lesson fees, club dues, Market payments and so on). Any cost in a post is only the host's note.
2.4 We do not guarantee any member's skill, identity, qualifications (such as coaching credentials) or the condition of items. Levels, attendance rates, manner scores and badges are reference information calculated from members' records and reviews.
3. Adults only
3.1 Only adults may use the Service: 19 or older in Korea and 18 or older elsewhere.
3.2 Accounts created with a false age will be suspended or deleted.
4. Accounts
4.1 You sign up with Apple, Google or email. You must not create several accounts to avoid sanctions or manipulate reviews.
4.2 You must not post a false profile (age, gender, photos, level or qualifications) or impersonate anyone.
4.3 You are responsible for your account and must not lend or sell it.
4.4 You can leave at any time from the profile button (top right) > Settings > Delete account. What happens is described in section 5.4 of the Privacy Policy. Subscriptions are not canceled automatically; cancel them in the store (9.4).
5. Community rules
The following are not allowed.
5.1 Breaking commitments
- No-shows and repeated late cancellations.
- False or colluding attendance marks, match results or reviews.
5.2 Bad manners
- Swearing, verbal abuse, threats, harassment, or violence during play.
- Belittling others' skill or appearance.
5.3 Sexual approaches
- Unwanted sexual messages or photos, comments on someone's body, or requests for physical contact.
- Sexual approaches disguised as lessons or games.
- Soliciting or arranging prostitution or paid "meetups".
- Repeated contact after being turned down, following someone, or other stalking.
5.4 Hate and discrimination
- Hateful or discriminatory content based on gender, age, disability, origin, race, religion, sexual orientation or similar grounds.
5.5 Fraud and abuse

- Collecting or spreading other members' personal information.
- Impersonating other people or organizations.
5.6 Moving contact off the App and spam
- Asking for outside messenger IDs, phone numbers or bank accounts, or pushing others off the App. (Members may decide what is needed to complete a Market trade, but we sanction it when used for fraud.)
- Advertising, promotion, repeated posts, or mass commercial messages.
5.7 Illegal content
- Pornography, content that infringes copyrights or portrait rights, and anything that breaks the law.
6. No-shows and sanctions

- Canceling within 3 hours: late cancellation (weight 2).
- Not showing up: one no-show.
- Late cancellations totaling weight 4 count as one no-show.
- A host who cancels a post gets a late cancellation (weight 2). Cancellations for too few players or rain have no effect.
6.2 Attendance is confirmed when at least two of check-in, the host's mark and other participants' marks agree. If only one marks you absent, you can dispute it within 48 hours.
6.3 No-show sanctions (no-shows in the last 90 days)
| No-shows | Action |
|---|---|

| 2 | Cannot join posts for 7 days |

6.4 Other violations of section 5 lead to a warning, hidden posts or messages, a 7-day suspension, a 30-day suspension or a permanent ban, depending on severity. Sexual approaches, stalking, fraud and violations involving minors may lead to an immediate permanent ban.
6.5 You can appeal a sanction by email (section 18). We will tell you the result.
7. Dating introductions
7.1 Dating introductions are off unless you turn them on. Only members who complete identity verification can turn them on.
7.2 One-to-one chat opens only after both members like each other.
7.3 Safety tips
- For a first meeting, we suggest playing together at a busy public court.
- Do not share your home address, workplace or financial details before meeting.
- Report anyone who asks to borrow money or suggests investments.
- Tell someone you trust when and where you are meeting.
- If you feel uncomfortable or unsafe, leave right away and block and report the member in the App. In an emergency, call local emergency services (112 in Korea).
7.4 Identity verification confirms only age and identity. We do not check or guarantee criminal records, marital status or the truth of profiles.
7.5 Meetings between members and their outcomes are each member's own decision and responsibility. We still act on reports under section 13 and respond to lawful requests from law enforcement.

- Reselling court bookings or event entries at a markup.
- Items you do not have, or listings using other people's photos.
8.4 Sellers must describe condition, defects and price truthfully.
8.5 Be careful with anyone who asks for prepayment. Where possible, meet in person and check the item before paying.
8.6 When fraud is reported, we hide the listing right away and apply sanctions under 6.4. In disputes between members, we cooperate to the extent required by law (checking report records, providing information to law enforcement on request, and so on).
