vibe-mod — Privacy Policy

Effective date: 2026-05-27 (hackathon submission) App: vibe-mod on Reddit Developer Platform (Devvit)

1. The short version

vibe-mod sees Reddit posts and comments inside your subreddit only, to evaluate the rules you wrote.
vibe-mod sends only your typed English rule description to OpenAI. It does not send any Reddit user content (post bodies, comment bodies, usernames, vote history, browsing history, DMs) to OpenAI or anywhere else.
vibe-mod stores rules, audit entries, and rollback tokens in Reddit's Devvit Redis, scoped to your subreddit. Reddit handles the underlying storage.
vibe-mod retains audit entries for 30 days, then deletes them automatically.
vibe-mod does not train any AI model on your data.

2. What we collect, and why

Category	What it is	Why we need it	Where it lives	Retention
Mod rule input	The English sentence a moderator types into the "Compose rule" form	To translate it into a structured rule	Sent to OpenAI (`api.openai.com`) for compilation; the compiled JSON is stored in Devvit Redis	Indefinite (until the moderator deletes the rule)
Rule definitions	The compiled JSON rule	To evaluate posts and comments	Devvit Redis (Reddit-hosted, subreddit-scoped)	Indefinite (until deletion)
Audit entries	A log row per moderation action vibe-mod took	To let your mod team see what happened and undo it	Devvit Redis	30 days, then auto-deleted
Rollback tokens	A serialized reversal blob per action	To support the "Undo" menu action	Devvit Redis with 30-day TTL	30 days
Author cache	A short cache of an author's account age and karma	To avoid a Reddit API roundtrip on every event	Devvit Redis	1 hour
Compile rate counters	A daily counter of how many rule compiles a sub has used	To enforce the per-day rate limit	Devvit Redis	1 day

3. What we do not collect

We do not collect end-user personal data. End users of your subreddit are not vibe-mod users.
We do not send post bodies, comment bodies, or usernames to OpenAI or any other third party. The LLM never sees Reddit content.
We do not run any analytics or tracking. No third-party trackers, no Google Analytics, no Segment, no Sentry.
We do not collect data from other subreddits. Each installation is sandboxed by Devvit.

4. Third parties

Reddit (Devvit) — hosts the app and the Redis data. Subject to Reddit's privacy policies.
OpenAI — receives the moderator's typed rule sentence and the vibe-mod system prompt. We use the gpt-5.4-nano model by default (and offer gpt-5.4-mini or older fallbacks as configurable). Subject to OpenAI's API data usage policies. OpenAI states API data is not used to train their models by default.

No other third parties receive data from vibe-mod.

5. End-user transparency

Every moderation action vibe-mod takes appears in the standard Reddit moderation log with the prefix vibe-mod: . End users see the same removal reasons and modmail messages they would see for any other moderator action. vibe-mod does not contact end users directly outside of these standard moderation channels.

6. Data deletion

A moderator can delete a rule at any time from the vibe-mod Dashboard. Deletion removes the rule from rules:active immediately.
A moderator can request deletion of audit entries by writing a one-time menu action (planned for v0.2) or by waiting for the automatic 30-day expiry.
Uninstalling vibe-mod from a subreddit removes all vibe-mod data scoped to that subreddit. Reddit's Devvit storage rules govern the actual deletion semantics.

7. Children

vibe-mod is a tool for subreddit moderators, who must be at the age of majority in their jurisdiction to use Reddit's developer features. vibe-mod is not directed at children under 13.

8. Region

vibe-mod stores data wherever Reddit's Devvit infrastructure stores it. We do not control the region of Devvit's data centers.

9. Security

API keys (OpenAI) are stored as Devvit App-scope secrets, encrypted by Reddit. They are only readable by app server code; they are not visible to subreddit moderators or to anyone via the UI.
Audit entries are stored in Devvit Redis, namespaced per installation. They are not accessible across subreddits.
All HTTP traffic (to OpenAI) goes over HTTPS.

10. Changes

This policy may be updated. The effective date above reflects the most recent version. Material changes will be announced in the app's update notes.
