Is Harmony Control free to join?

Yes. Everyone registers for free. No credit card is required to create an account or accept a relationship invitation.

Do submissives need a paid subscription?

No. Submissives join and participate for free. Paid plans are optional upgrades—usually for Dominants who want more relationships or advanced tools.

Can a submissive have more than one Dom?

Yes. You can have multiple relationships with different Doms, each tracked separately. You cannot have two relationships with the same person.

How do AI relationships and the human messenger differ?

An AI companion (AI Dominant or AI Submissive) has their own relationship and chat bubble using the AI message allowance on Pricing. A human couple gets a private messenger bubble between the two of them that does not spend the AI allowance.

How do I get started?

Register free with a username and password (email is optional), then invite your partner, browse Members, enter the Chains of Harmony Academy, or meet an AI companion.

Q: What is Harmony Hub?

Harmony Hub is a private space in each relationship to record boundaries, limits, wants, needs, likes, preferences, fantasies/desires, values, and beliefs so agreements stay clear.

Join for free, then upgrade when you want more. Here is how accounts and relationships work.

Accounts & subscriptions

Free for everyone

Register with no credit card. Every account starts on the Free tier with core features: relationships, Harmony Hub, contracts & rules, Day Board, behaviour tools, and more.

Join free—upgrade optional

Everyone starts on the Free tier. Submissives can participate in a dynamic without a paid plan. If your Dom upgrades, you still benefit from their tier inside that relationship.

Dom & power-user plans

Explore is free: 1 relationship and 2 introductions a month. Connection is $7.99 CAD: 10 introductions. Devotion is $14.99 CAD: up to 3 relationships and 30 introductions. Sovereign is $24.99 CAD: unlimited relationships and introductions.

Store (optional)

Digital task packs and add-ons are separate from monthly subscriptions. Subs may eventually gift packs to their Dom — we're still shaping that.

A private space in each relationship to record boundaries, limits, wants, needs, likes, preferences, fantasies/desires, values, and beliefs — so agreements don't get lost and trust can deepen over time.

Harmony Control is built for consensual power-exchange dynamics, but the same tools — honest limits, clear agreements, daily structure — strengthen any relationship that values clarity and growth.

Mistress Seraphina or Master Adrian stays with your account. You can change the portrait. That changes how they look, not who they are. Ask how something in the app works. You can decline any suggestion. With a human partner the coach stays in the corner. With an AI companion the coach moves into the notifications bell.

An AI companion has their own relationship and their own chat bubble. Those replies use the AI allowance on Pricing. A human couple, when that relationship is selected, each gets a messenger bubble to talk back and forth. Those messages stay between the two of you and do not spend the AI allowance.

Register free with a username and password (email is optional), then invite your partner (as a Dom) or accept their invitation (as a Sub). Start with Harmony Hub and contracts when you are ready. How to use an anonymous account is on Updates.
