Real moments shared with real people. No ads, no attention hacking, no Zuckerberg.
1Getting Started
1.1 Creating Your Account
- Language: Choose from English, Spanish, French, or Italian.
- Sign Up: Enter your email, username, display name, and birth date (Sunslider is only for users 16 and up).
- Invitation Codes: If someone invited you to Sunslider, insert your invitation code to help you find them and other friends already on Sunslider.
- Your Interests: Select at least 3 interests to help discover relevant content/new people to follow.
1.2 Setting Up Your Profile
- Profile Picture: Upload a photo or take a new one using the Sunslider camera; crop your photo to fit the frame.
- Display Name: In addition to your username, you can also choose to have a display name that others will see as you post content on Sunslider.
- Bio: Tell the people a little about yourself (150 characters max).
2Privacy Protection
2.1 Automatic Privacy Features
Sunslider automatically protects your privacy by removing:
- Location data from all photos
- Device information (phone model, camera settings)
- Hidden timestamps and metadata
This happens automatically for every photo you upload - no action is needed on your part. This is part of our "no ads" guarantee: we'll never sell your data, not least because we simply don't have it.
2.2 Three-Level Privacy System
Every post (slide in Sunslider parlance) and story (My Days) has its own privacy settings:
- Everyone: Public content anyone can see
- Followers Only: Only people who follow you can see
- Mutuals Only: Only people you follow AND who follow you back
You can set your default privacy levels in Settings; these will be applied to your posts, but you can always choose a different privacy level for each individual post.
3Sharing Content

8Content Guidelines and Reporting Inappropriate Content
Sunslider's content moderation policies are listed here. We believe that a community can enjoy both freedom of expression and effectively monitor bad actors, and for that we rely on your input as well.
8.1 Reporting Inappropriate Content
If you see a slide or other content that you feel goes against our published guidelines, you can report it using the following process:
- Report Function: Use the "Report" function available in the … menu when viewing specific content
- Report Process: The report will be sent to us automatically and treated as quickly as possible
- Report Outcomes: We'll keep you informed of any actions we take, which can range from nothing (if we feel the content doesn't actually go against our guidelines), to a warning to the offending user, to an outright ban
8.2 Blocking Content
For content and/or users that you simply don't want to see, even if it doesn't go against our content guidelines, we have a "block" function that lets you remove them from your Sunslider experience: you won't see them, they won't see you. You can manage your blocklist in your Settings.
