These Community Guidelines are Milo’s user policy for user-generated content (UGC). They are part of the Terms of Service and support Google Play’s UGC and Child Safety requirements. By sending letters or messages, you agree to follow them.
1. What Milo is for
Milo is for thoughtful, respectful letter exchanges between users aged 16+. Write as you would to a stranger you hope to meet again—not as a channel for abuse, spam, or illegal content.
2. Prohibited content and behavior
Do not create, send, solicit, or promote:
- Child sexual abuse and exploitation (CSAE), CSAM, grooming, sexualization of minors, or any content that endangers children (see Child Safety Standards)—zero tolerance;
- Sexual content involving anyone 17 or under, or requests for sexual content from minors;
- Violent threats, terrorism, or content that incites imminent harm;
- Hate speech or harassment based on protected characteristics;
- Bullying, stalking, or repeated unwanted contact after a block;
- Fraud, scams, phishing, or impersonation of people or organizations;
- Non-consensual intimate imagery or doxxing;
- Malware, spam, or unauthorized commercial advertising;
- Requests for or sharing of others’ government IDs, payment card numbers, passwords, or precise home addresses;
- Attempts to circumvent moderation, stamps, rate limits, or anonymity / pen-pal rules;
- Any other illegal content under applicable law.
3. How moderation works
- Automated checks — Sensitive-word filters and third-party text moderation may run when you send letters or replies.
- Mild / salvageable issues — Content that can be fixed may be returned to you with a reason. On eligible send paths, stamps may be refunded so you can revise and resend from Sent mail.
- Severe / malicious content — Content we treat as unsalvageable or abusive may be rejected silently: you may receive no notification, stamps are not refunded, and the item may be hidden from your sent list.
- Human review — Reports and escalations may be reviewed by our safety / admin team. We may remove content, ban accounts, or take other actions without prior notice when needed for safety.
No filter is perfect. If something harmful gets through, report it.
4. Report, block, and archive (in-app)
Google Play requires UGC apps to provide in-app ways to report and block. In Milo you can:
- Archive / hide certain letters or messages from your view without sending a formal report;
- Report and block from letter detail and mailbox thread readers—this files a safety action for review, blocks the other user where applicable, and may dissolve pen-pal relationships;
- Child safety / CSAE reports from Profile → Report safety concern (opens email or these standards);
- Email support@z-rex.net with usernames, message/letter IDs, dates, and a short description.
If someone is in immediate danger, contact local emergency services first.
5. Pen pals and privacy
- Do not pressure others to share real-world contact details, photos of minors, or payment information.
- Respect virtual anonymity until both sides accept a pen-pal relationship.
- Do not share another user’s private letters outside the app without their consent, except as needed for legitimate safety reporting to us or authorities.
6. AI Drifter
If you opt in to AI fallback replies, an automated “AI Drifter” may respond when no human does in time. Treat AI replies as machine-generated. Do not use AI opt-in to solicit prohibited content. AI identities cannot become pen pals.
7. Enforcement
Depending on severity and history, we may: warn; remove or hide content; refund or forfeit stamps; limit features; suspend or permanently ban accounts; preserve records; and report to law enforcement or NCMEC / regional hotlines when required. Appeals: email support@z-rex.net with your registered email and details. We are not obligated to restore every decision.
8. Updates
We may update these Guidelines. The current version is always on this page. Material changes may also be referenced in the Terms.
