LITTLE SOFTWARE COMPANY LLC, doing business as Tummi (“Tummi,” “we,” “us,” or “our”), provides the Tummi mobile app, website, and related services (the “Service”).
This policy explains what information we collect, how we use it, who receives it, and the choices available to you. Tummi is designed for parents and caregivers.
For privacy questions or requests, contact privacy@tummiapp.com.
Information you provide may include:
We and our service providers also collect information as you use the Service, including:
We may associate this information with your account. Identifiers such as hashed email addresses can still be associated with an individual and are not necessarily anonymous.
Our website and service providers may use cookies, local storage, and similar technologies to operate the Service, remember preferences, measure usage, and support advertising attribution.
We use information to:
We may create aggregated or de-identified information for research, reporting, and product improvement. We treat information that remains reasonably linkable to a person as personal information.
To provide AI features, we send relevant information to AI and search providers. This can include your messages, submitted images, conversation history, feeding information, and other context needed to respond to your request.
Our providers include OpenAI, OpenRouter and the model providers accessed through it, and Exa for web searches. Search queries generated from your request may be sent to Exa.
Information sent for AI processing may contain personal information you provide. We do not represent all AI requests as anonymous or de-identified.
For our current OpenAI and paid-model use through OpenRouter, we have disabled the optional training-sharing settings identified in those services. Providers may still process and retain information to deliver their services, maintain security, prevent abuse, and meet legal requirements under the applicable agreements.
We also use service providers to monitor AI performance and troubleshoot issues. This processing can include AI inputs and outputs.
We disclose information to the following recipients for the purposes described in this policy.
We use providers for hosting, storage, authentication, analytics, diagnostics, AI processing, subscriptions, communications, and support. These providers receive information needed for their work on our behalf, subject to the applicable agreements.
We use Appstack to measure advertising performance and connect advertising campaigns with activity in Tummi. Appstack receives app events and identifiers, including name and email information supplied when you sign in, where available.
Through our configured Appstack integrations, information is shared with advertising platforms, including Meta, which operates Facebook and Instagram, and TikTok. This supports conversion measurement, attribution, and optimization of advertising for Tummi.
The information involved can include:
The information a particular advertising platform receives depends on the integration, event, available identifiers, and applicable settings. Advertising platforms may match information they receive with information they already hold, subject to their terms, privacy policies, and applicable restrictions.
These advertising disclosures are separate from providers processing information solely on our behalf.
If you use features to share content with another caregiver, community members, or other recipients, we disclose the information needed to carry out that action.
We may disclose information when necessary to comply with legal requirements, respond to valid legal processes, protect people or the Service, or address fraud and security issues.
Information may also be transferred as part of a merger, acquisition, financing, or sale of business assets, subject to applicable privacy requirements.
We do not exchange personal information for money. Advertising-related disclosures may nevertheless qualify as a “sale” or “sharing” under certain privacy laws.
We retain information such as feeding activity, preferences, and conversation history to provide continuity and personalize your experience.
You can request deletion or a reset of this information by contacting privacy@tummiapp.com. Some information may need to be retained as explained below.
Tummi is intended for adult parents and caregivers. It is not intended for children to create accounts or use independently.
Parents and caregivers may provide information about their children when using feeding and personalization features. We handle that information as described in this policy.
We do not knowingly collect information directly from children under 13. If you believe a child has independently provided information to us, contact privacy@tummiapp.com so we can investigate and take appropriate action.
We retain personal information for the purposes described in this policy. Retention depends on the type of information, the features you use, account status, and legal, security, or operational requirements.
You can request account deletion through our delete account page. For requests concerning particular information, contact privacy@tummiapp.com.
We may retain information where necessary to meet legal obligations, prevent fraud, resolve disputes, or establish and defend legal claims. Backup copies may remain until removed through the applicable backup cycle.
Information held by advertising platforms or other independent recipients may also be subject to their retention practices and your rights with those recipients.
We and our providers may process information in the United States and other countries. Privacy laws in those countries may differ from those where you live.
Where required, transfers are subject to appropriate safeguards, such as contractual protections or other legally recognized transfer mechanisms.
We use administrative, technical, and organizational measures to protect personal information. No transmission or storage system can guarantee complete security.
Please protect your account credentials and contact us if you suspect unauthorized access.
Depending on your location and the applicable law, you may have rights to:
Contact privacy@tummiapp.com to make a request. We may need information to identify the relevant account and, where appropriate, verify your identity.
Your device and advertising-platform settings may provide additional controls over advertising identifiers and personalized advertising. Their effect depends on the platform; changing those settings does not necessarily stop every transfer described in this policy.
Where the California Consumer Privacy Act applies, California residents may have rights to know, access, correct, and delete personal information, and to opt out of its sale or sharing for cross-context behavioral advertising.
The advertising disclosures described in Section 5 may constitute sale or sharing under California law, depending on the recipients’ use of the information and the applicable arrangements. We do not make a blanket claim that advertising-related sharing never occurs.
To submit a privacy request, including a request to opt out of advertising-related sale or sharing, contact privacy@tummiapp.com and describe your request.
We will handle requests as required by applicable law and will not unlawfully discriminate against you for exercising your privacy rights.
Where EU or UK data protection law applies, our processing must have an applicable legal basis. Depending on the activity, that basis may be:
Where consent is required for a particular activity, including certain advertising or tracking activities, that requirement applies separately from this policy. You may withdraw consent by contacting us or using the applicable controls.
You may also complain to the relevant data protection authority.
You may have additional rights under the laws where you live, including rights relating to targeted advertising or appeals of privacy-request decisions.
Contact privacy@tummiapp.com to ask about or exercise applicable rights.
The Service may link to or integrate with services operated by other organizations.
Their privacy policies explain how they handle information in their own services. This policy explains the disclosures we make through Tummi; another organization’s policy does not replace our responsibilities for those disclosures.
We may update this policy as our services, practices, or legal obligations change. We will update the date above when we revise it.
Where required, we will provide additional notice or request consent before a change takes effect.
