Pike Calc Privacy Policy

Updated 15 November 2026. The app information on this page is based on Pike Calc version 1.0, build 2. It has been checked against that version’s source code; the version installed on your device and its behaviour have not been independently confirmed. Contact support if your version differs. Further information about our email provider’s processing arrangements is still pending.

Who we are

Craig is the only person at TallyTrowel who accesses the support mailbox. Service providers also process messages to deliver their services.

TallyTrowel Pike Calc is provided by Craig Bradshaw, trading as TallyTrowel. Craig Bradshaw is responsible for personal information received through support enquiries. Contact support@tallytrowel.com with privacy questions or requests.

This policy covers Pike Calc only. Other TallyTrowel products have different data arrangements. Visiting this website is covered by our website privacy information.

Calculations stay on your device

Pike Calc performs its calculations offline. The current app does not send calculations or project references to TallyTrowel servers. It contains no advertising, analytics or third-party crash-reporting SDKs, and does not require an account.

The app stores saved pikes and the current calculator draft in its local app storage. This includes dimensions, masonry choices, calculation settings and any pike reference you enter. References can contain personal information if you choose to enter names, addresses or other identifying details. We cannot access these local records remotely.

The current version does not access your location, contacts, camera or microphone, or collect unique device identifiers.

Android backups and changing phones

Android backup is enabled in the app configuration. Depending on your device, settings and backup service, saved calculations and drafts may be included in a device backup or transferred when you change phones. These services are controlled by Android, your device manufacturer or your backup provider; TallyTrowel does not operate a backup server or have access to those backups.

Check your device's backup settings to manage this. Backup and restoration are not guaranteed. Restoring a backup may restore previously stored app data.

Deleting your calculations

Use Delete in Saved pikes to remove an individual saved entry.
Deleting a saved entry does not clear the current calculator draft. Use New pike to reset that draft. To remove the visible saved entries and reset the current draft within the app, delete the entries and use New pike. This is not a complete erasure of all app storage.
Android Settings also lets you clear the app's storage. Uninstalling removes the app's local data; a later backup restoration may bring data back.

Older migrated records may remain in local app storage even after you delete visible saved entries. To remove all app-local records, including that legacy storage, use Android Settings to clear the app’s storage. Copies in device backups may still be restored later.

These actions do not delete PDFs you have exported, printed documents, emails or backup copies held by other services. Manage those copies separately in the relevant app or service.

PDF reports and printing

When you choose to print or save a report, Pike Calc passes the report to Android's print system. You select the printer or PDF destination. The report contains the calculation information included in your chosen output. Your selected print, storage or cloud service may process that report under its own privacy terms. Pike Calc does not automatically upload reports to TallyTrowel.

Reporting a problem and contacting support

Reporting a problem opens a draft in your chosen email app. It includes the app version and build number, Android version, and device manufacturer and model. It does not automatically include saved pikes or unique device identifiers such as IMEI or Android ID.

You can review, edit or discard the draft before sending it. Once handed to your email app, the draft is handled under that service's settings and privacy terms, including any draft synchronisation. Pike Calc does not itself send the email.

If you send an email, we receive your email address, message, included technical details and any attachments you choose to add. We use these to respond to your enquiry and investigate problems. Providing this information is optional and is not required to use the calculator. Please include only information needed for your enquiry.

How we handle support correspondence

Business email is handled through Zoho Mail’s UK service. Support emails are not forwarded elsewhere. Provider processing is not necessarily confined to the UK. Our proposed lawful basis for using support correspondence is our legitimate interest in answering enquiries and maintaining a reliable app; our assessment of that basis is still being finalised. We do not use support correspondence for advertising or automated profiling.

We review enquiries and support correspondence every three months. At each review, we delete resolved correspondence where 12 months have passed since the last meaningful contact, unless it is still needed for an ongoing issue. This means routine deletion takes place at the next quarterly review after that period.

We delete unnecessary attachments or confidential details as soon as they are no longer needed. Records required for a dispute or legal obligation are kept separately for that purpose and reviewed when the need ends.

Deleting information from our mailbox may not immediately remove provider backups or copies held by other people.

Zoho processes email information to provide its service. See Zoho's privacy policy. We are awaiting clarification from Zoho about the processing locations and safeguards for international transfers applicable to our account. We will update this page when these details are confirmed.

Android and Google Play diagnostics

Separately from Pike Calc, Android and Google Play may collect device and app-quality diagnostics according to your device settings. Google may make app-quality reports available to developers through Android vitals. This is distinct from an analytics or crash-reporting SDK embedded in Pike Calc. See Google's usage and diagnostics information.

Your privacy rights

For personal information we hold in support correspondence, you can ask for access, correction, deletion or restriction, subject to the circumstances and applicable law.

You can object to processing based on legitimate interests. Email support@tallytrowel.com to make a request. We cannot retrieve or delete calculations stored only on your device; use the controls explained above.

You can also complain to the UK's Information Commissioner's Office (ICO).

Changes to this policy

This policy describes the current version of Pike Calc. We will review it when the app or our data-handling practices change and update the date shown on this page.
