FREE: scheduling and accountability tools.COSTS EXTRA: test kits and laboratory or professional testing, bought separately.

App Dependency Depends on the app. This page describes how the P in the Cup app is intended to work. The app is not live yet, and details may change before launch.

Family / Trust Planned

Agree once. Let the schedule decide.

When an adult in your family has offered to do voluntary testing, the hardest part is often not the test. It is the argument about when, who decided, and whether it was fair. Family mode is being designed so two consenting adults agree the rules once, and a fair schedule picks the days.

See the family agreement demo How consent works

The random scheduling and accountability service is free. Test kits and any laboratory testing are purchased separately.

Left: the participant's own view of a shared agreement and what they share. Right: the partner's limited view, showing only the status the participant approved.

For consenting adults only

Family mode is for adults who each choose to take part. Nobody under 18 can be enrolled. It is not a tool for checking up on someone who has not agreed, and it is not designed for courts, probation, schools or employers. The app has not launched; this page describes the planned design.

Why it helps

Less arguing. More follow-through.

A neutral schedule takes one recurring argument off the table, so the conversation can move on to how someone is doing.

No more "why today?"

When a family member picks the day, it can feel like a reaction to a mood or a disagreement. When the schedule picks it, nobody has to defend the choice.

Two equal adults

Both people review and accept the same written agreement. Neither one controls the other's account, and either can withdraw.

Sharing by consent

Each adult chooses which information the other may see, such as "checked in today". Detailed results are shared only if the person they belong to says so.

Step by step Planned

How it works for you

  1. Talk it through and draft an agreement

    Agree how often a test day might come up, which kind of test, how long the participant has to respond, and what each person will see. Agree a date to review it.

  2. Both adults accept it separately

    Each person reads the agreement on their own device and accepts it. Nothing starts until both have, and neither can change it later without the other's agreement.

  3. The schedule is chosen in advance

    Test days are chosen at random before each period, on the participant's device or on a data node the two of you choose, and sealed with a verifiable commitment. Nobody in the family picks a day, and nobody can reroll. Fair random scheduling.

  4. Follow through, and share what you agreed

    On a scheduled day the participant uses a separately purchased test, as agreed. The partner sees only the status the participant approved.

What each person sees Planned

Two views, one agreement

An example of how an agreement might divide visibility. The real settings are chosen by the two of you when you accept it.

The participant's view

  • Today's status: testing day or not
  • The full agreement and its review date
  • Their own check-ins, notes and any results they chose to record
  • A clear list of what the partner can see
  • Buttons to change sharing or withdraw

The partner's view

  • The same agreement
  • Only the items the participant approved, for example "checked in today"
  • A shared timeline, if both agreed to one
  • No location, no hidden checks, and no extra tests outside the schedule
  • Their own button to withdraw

Celebrations and badges are optional in family mode and switched on per person. Nobody's progress is shown to the other without permission, and there are no leaderboards.

Privacy model Planned

Your family's records, not ours

  • A private vault for each person. Each adult's own records are planned to live in an encrypted vault on their own device.
  • Sharing through storage you choose. To share across two devices, the plan is to sync through a data node you or someone you trust runs, or a sync provider you explicitly pick, not through P in the Cup's servers.
  • Not anonymous to each other. With only two people, there is no meaningful anonymity between you. Privacy here means each person controls what the other sees.
  • Honest limits. Sharing between two people always means some data is moved and stored somewhere. Software downloads and network traffic still carry ordinary risks. See Privacy Explained.

Starting the conversation

How to propose an agreement respectfully

  • Pick a calm moment, not the middle of a disagreement.
  • Frame it as something you build together: "Could a fair, random schedule make this easier for both of us?"
  • Invite the other person to shape the terms: how often, which test, and what gets shared.
  • Agree in advance how you will talk about a result neither of you hoped for, remembering that a home screen is preliminary. See how to choose a test kit.
  • Avoid labels like "clean" and "dirty". Talk about agreements, check-ins and goals.
  • If the answer is no, respect it.

Example persona

"Alex" and "Sam"

This example matches the sample screens above. Alex has offered to do voluntary testing while rebuilding trust with Sam. They agree on two to four test days a month, chosen in advance. Alex shares only whether a check-in was completed, not any result. Sam agrees not to ask for tests outside the schedule. They plan to review the agreement after 30 days, and either can end it. Alex buys the test kits; the schedule itself costs nothing.

Questions

Family mode FAQ

Can my partner see everything?

No. Each adult chooses which items the other may see, and the agreement lists them before either of you accepts. Detailed results are visible only if the person they belong to shares them.

Can we use this for a teenager?

No. Family mode is only for consenting adults. Enrolling anyone under 18 is not supported.

What happens if one of us wants to stop?

Either adult can withdraw from the agreement at any time, without the other's permission. The agreement then ends for both.

Who chooses the test days?

Neither of you. Days are chosen at random in advance on a device or data node you control and sealed with a commitment, so checking again cannot change them.

Does a negative home test prove anything?

A home test is a screening test that covers only the substances and time window it is designed for. It is not proof of sobriety, and an unexpected result may need laboratory confirmation. See the Test Kit Guide.

Is any of this free?

The random scheduling and accountability service is free. Test kits and any laboratory testing are purchased separately.
